Iran’s Islamic Revolutionary Guard Corps (IRGC) has announced the closure of the Strait of Hormuz, accusing the United States of violating a ceasefire agreement. According to a statement reported by Al Jazeera, the IRGC said the closure would take effect from Saturday evening and remain in place until further notice. The group alleged that while several ships had crossed the strait the previous day, the U.S. failed to lift its naval blockade on Iranian vessels and ports, which it described as a breach of the ceasefire terms.

The IRGC warned all ships in the Persian Gulf and the Sea of Oman not to leave their anchorages, cautioning that any vessel approaching the Strait of Hormuz would be considered as cooperating with the enemy and could be targeted. It instructed ship operators to follow only official IRGC Navy communications and Channel 16 directives. The statement also dismissed the U.S. president’s remarks on the region as unreliable and unacceptable.

The closure raises immediate concerns for maritime traffic and regional stability, though no timeline for reopening was provided.

Iran’s Supreme Leader Mojtaba Khamenei praised the country’s army, saying that the weaknesses of the United States and Israel have been exposed to the world. According to the state news agency Tasnim, Khamenei delivered his message on the occasion of Army Day, extending greetings to soldiers, their families, and the nation.

He stated that the victory of the Islamic Revolution ended the era of weakness imposed on the army by enemies and commended the military’s recent acts of bravery in defending the country. Khamenei further claimed that Iran’s armed forces have stood firmly against US conspiracies, the legacy of the Pahlavi regime, and separatist groups seeking to divide the nation.

Khamenei added that Iran’s resistance against attacks from Israel and the United States has revealed their weakness and humiliation before the world.

Iran has remained largely disconnected from the global internet for nearly 50 consecutive days, according to monitoring group NetBlocks. The organization stated in a post on social media platform X that the country has been effectively cut off from international networks for about seven weeks, calling the prolonged digital blackout highly unusual in the modern world.

BBC Arabic reported that the Iranian government has begun gradually easing communication restrictions, with some media outlets noting that internet services are being partially restored. After nearly 50 days of disruption, access to various Google services has resumed, though users continue to experience significant connectivity issues.

Due to limited access, many Iranians have turned to satellite-based internet options such as Starlink, which reportedly costs around six dollars per gigabyte. With the country’s average monthly income estimated between 200 and 300 dollars, the expense has become a heavy burden for ordinary citizens.

Iran’s Supreme Leader Ayatollah Mojtaba Khamenei has declared that the country will continue its resistance against what he called 'arrogant and infidel powers.' In a message marking Iran’s Army Day, shared on the social media platform Telegram, Khamenei praised the Iranian military for exposing the 'weakness and humiliation' of its enemies. He claimed that Iranian drones are striking 'American and Zionist criminals like thunder,' and said the navy is ready to inflict new defeats on adversaries.

Khamenei described the current conflict as a continuation of Iran’s revolutionary tradition, linking it to the 1979 Islamic Revolution and previous 'imposed wars.' He called the army 'part of the people’s hearts' and 'true sons of the nation.' The message also paid tribute to his late father and predecessor, Ayatollah Ali Khamenei, who was killed at the start of the war in February and was credited with strengthening the army.

Mojtaba Khamenei, who assumed leadership after his father’s death, has not appeared in public since taking office. He concluded his message by expressing condolences to the families of those killed in the 'war imposed by the United States and the Zionist regime.'

Iran’s Revolutionary Guard Corps (IRGC) has permitted limited ship movement through the Strait of Hormuz despite U.S. sanctions. The decision, made within the past hour, is being described as a gesture of goodwill, though the overall situation remains tense. Iran has allowed passage only for vessels it does not consider hostile and has announced plans for a new control system in the strategic waterway.

A recently released IRGC map labels southern waters near Oman as a “danger zone” while marking Iran’s coastal routes as “safe zones,” signaling Tehran’s intent to assert greater authority over the strait. Iran is also considering a toll collection system, which it views as a means to recover war-related losses. Broader negotiations remain unresolved, with Iran demanding an end to regional conflict, security guarantees, sanctions relief, the return of frozen assets, and improved regional ties.

The situation remains fragile, and uncertainty continues to dominate, making near-term diplomatic progress difficult according to the report.

Iran has maintained control over the Strait of Hormuz despite suffering naval losses from joint U.S. and Israeli strikes. Using small, fast boats collectively known as the “Mosquito Fleet,” Tehran continues to pressure U.S. forces in the region. The Islamic Revolutionary Guard Corps (IRGC) deploys these vessels separately from Iran’s regular navy, capable of launching drones and missiles from hidden coastal bases. On Friday, Iranian Foreign Minister Abbas Araghchi announced via social media that the strait had been fully reopened, a move welcomed by U.S. President Trump, who said American port blockades would remain until a peace deal is reached.

Experts describe the IRGC’s naval tactics as guerrilla-style, relying on surprise attacks rather than conventional warfare. Analysts note that many of the small boats are difficult to detect by satellite and can be deployed within minutes from concealed bases along Iran’s rocky coast. The IRGC’s maritime force, numbering around 50,000 personnel, operates across five sectors and maintains at least ten secret bases along the Gulf.

U.S. naval officials and analysts warn that these small, fast attack boats, along with drones and missiles, continue to pose a serious threat to commercial shipping in the Gulf and the Strait of Hormuz.

Many vessels are still avoiding the Strait of Hormuz despite Iran’s announcement that the key waterway is open to all commercial shipping. Maritime transport expert Jean-Paul Rodrigue of Texas A&M University told Al Jazeera that contradictory information from multiple sides has kept many ships from using the route. He said that although some vessels have attempted to pass through since the announcement, many have turned back due to ongoing uncertainty.

Iranian Foreign Minister Abbas Araghchi earlier declared the strait fully open to commercial traffic. However, Iranian Parliament Speaker Mohammad Bagher Ghalibaf warned that if the United States continues to impose blockades on Iranian ports, the strait would not remain open. Rodrigue noted that major shipping companies such as Maersk would only feel comfortable resuming transit once all Iranian restrictions or controls are completely lifted.

The situation underscores the fragile security and trade environment in one of the world’s most critical maritime chokepoints, with uncertainty still shaping global shipping decisions.

Within a 24-hour period, both the United States and Iran issued a series of major and often contradictory statements concerning the Hormuz Strait. On Friday, Iranian Foreign Minister Abbas Araghchi announced on X that the strait would remain fully open for the remainder of the ceasefire period. Minutes later, Donald Trump responded on Truth Social, thanking Iran but confirming that the US naval blockade on Iranian ports would continue until all transactions with Iran were fully completed.

Following a virtual meeting with about 40 countries, UK Prime Minister Keir Starmer and French President Emmanuel Macron said they would lead an international mission to safeguard freedom of navigation once conditions allowed. Hours later, Iranian Parliament Speaker Mohammad Bagher Ghalibaf dismissed Trump’s claims as false and warned that the strait would not remain open if the blockade persisted.

By Saturday, maritime tracking data showed some ships passing through the strait, but Iran’s military later announced it was reasserting control, citing US noncompliance. Shortly afterward, several vessels reportedly reversed course, signaling renewed uncertainty over the waterway’s status.

Iran’s Deputy Foreign Minister Saeed Khatibzadeh said U.S. President Donald Trump “talks too much” while speaking to reporters on the sidelines of the Antalya Diplomacy Forum in Turkey. He made the comment in response to Trump’s recent threat that the United States might “start bombing again” if no agreement is reached by next Wednesday.

Khatibzadeh stated that the U.S. president’s remarks were self-contradictory and unclear about what he actually meant. He emphasized that Iran believes war cannot bring any positive outcome but asserted that the country is ready to defend itself if attacked.

He added that Iran would continue fighting “until the last Iranian soldier,” underscoring Tehran’s stance on self-defense amid rising tensions. The comments were reported by Al Jazeera.

The United Kingdom has called on Iran to fully reopen maritime traffic through the Strait of Hormuz. British Foreign Secretary Yvette Cooper made the appeal during a meeting on the sidelines of the Antalya Diplomacy Forum in Turkey. She noted that while discussions to end the war are ongoing and a ceasefire is in effect, normal navigation through the strait has not yet resumed. Cooper emphasized that restoring maritime operations is essential for the global economy and urged that the current ceasefire be turned into lasting peace.

In response, Iran announced renewed restrictions over the Strait of Hormuz. The Islamic Revolutionary Guard Corps (IRGC) Joint Military Command stated that due to continued U.S. naval blockades, the situation in the strait has reverted to its previous state. The IRGC also accused the United States of engaging in piracy-like activities under the guise of a blockade.

The developments highlight ongoing geopolitical friction in one of the world’s most critical maritime routes, with implications for global trade and regional stability.

Iran has announced renewed restrictions on navigation through the Strait of Hormuz, citing continued U.S. naval blockades. The Islamic Revolutionary Guard Corps (IRGC) joint military command stated that the situation in the strategic waterway has reverted to its previous state due to what it described as ongoing U.S. obstruction. According to Iran’s state media, the IRGC accused the United States of engaging in piracy and maritime theft under the guise of a blockade.

The IRGC declared that the Strait of Hormuz is now under the armed forces’ strict management and control, with vessel movement limited as before. It warned that these restrictions will remain until full freedom of navigation for Iran-bound ships is restored. The announcement signals a renewed phase of tension in one of the world’s most critical energy supply routes.

Observers note that the situation raises concerns about potential disruptions to global energy flows, as the Strait of Hormuz remains a vital passage for international oil transport.

The U.S. Central Command (CENTCOM) reported that 21 ships have returned to Iran since the start of the U.S. naval blockade. The announcement came as Iran declared that it had reopened the Strait of Hormuz to all commercial vessels. According to CENTCOM’s post on social media platform X, the blockade began on April 13 at Iranian ports located in the Persian Gulf and the Gulf of Oman.

Iran’s parliament speaker, Bagher Ghalibaf, warned that the waterway would be closed if the United States did not lift its blockade in the region. Shipping companies have remained cautious about transiting the strait, and only a few vessels passed through the key maritime route on Friday.

The developments highlight heightened tensions in the Persian Gulf, with both U.S. and Iranian actions affecting global shipping routes and regional stability.

Delegations from the United States and Iran are expected to meet for a second round of talks on Monday, according to a CNN report citing Iranian sources. The meeting is reportedly scheduled to take place in Pakistan, though US officials have not confirmed the timing. US President Donald Trump commented that positive developments are underway and mentioned Lebanon as part of the process.

Trump added that the process would move quickly since most issues have already been discussed and agreed upon. The first round of talks between the two sides took place on April 11 in Islamabad, Pakistan, but ended without any agreement.

The upcoming meeting follows the earlier inconclusive discussions, suggesting continued diplomatic engagement between Washington and Tehran despite the absence of confirmed details from the US side.

Analysts have interpreted U.S. President Donald Trump’s recent optimistic comments about a possible agreement with Iran as a sign of a real opportunity, though they caution that the situation remains uncertain. The remarks, reported on April 18, 2026, have drawn attention for suggesting that Trump may be sincere in seeking a resolution after years of tension between the two countries.

Mohammad Elmasry, a professor at the Doha Institute for Graduate Studies, told Al Jazeera that while Trump’s statements may be somewhat exaggerated, there are reasons for cautious optimism. He noted that Trump’s confident tone and continued efforts to find a solution could indicate genuine intent to reach a deal. However, Elmasry warned that the United States and Iran still differ significantly on key issues, and compromise would be necessary for progress.

Elmasry concluded that the current situation offers more questions than answers, underscoring the uncertainty surrounding any potential agreement.

Iran has partially reopened its airspace, allowing international flights to pass over the country’s eastern region. The Civil Aviation Authority announced on Saturday that the airspace had been reopened for transit and that several airports resumed operations at 7 a.m. local time.

Despite the reopening, flight tracking websites indicated that more than three hours later, no international flights had yet crossed Iranian airspace. Several flights were observed taking longer routes to avoid the area, suggesting continued caution among airlines.

The report, citing The Guardian, did not specify the reasons behind the earlier closure or the partial reopening, leaving the broader context of Iran’s airspace restrictions unclear.
