U.S. President Donald Trump has issued a warning to Iran over its activities in the Strait of Hormuz. In a social media post on April 10, 2026, he accused Iran of behaving 'very badly' regarding the passage of oil tankers, saying such actions violate existing agreements. Trump claimed that Iran was reportedly charging fees from tankers passing through the strait and urged Tehran to stop immediately.

His remarks have heightened tensions just two days after a ceasefire between the United States and Iran took effect. Earlier, Trump had announced that if Iran fully, immediately, and safely reopened the Strait of Hormuz, the United States would suspend military operations for two weeks.

The Strait of Hormuz, a vital route for global energy supply, has not yet returned to normal operations. Since the conflict began on February 28, shipping through the area has remained limited, raising concerns about stability in the region.
