Iranian Foreign Minister Abbas Aragchi held several phone conversations with foreign ministers from various countries to discuss regional security and the evolving situation, according to Al Jazeera citing Iran’s state news agency IRNA. During talks with the foreign ministers of Azerbaijan and Turkmenistan, Aragchi addressed recent U.S.-Israeli attacks near Caspian Sea provinces, warning that such actions could pose security and environmental risks.

Earlier, Aragchi spoke with Pakistan’s foreign minister about ensuring the country’s “sustainable security” and also contacted counterparts in Oman, South Korea, Azerbaijan, and Turkmenistan. In his discussion with South Korean Foreign Minister Cho Hyun, both sides expressed concern over the potential economic impact if the Strait of Hormuz were to be closed.

Aragchi stated that the instability in this vital maritime route was a direct result of what he described as “illegal attacks” by the United States and Israel.
