NEWSAR · AI

On day 51 of the US-Iran conflict, tensions remain high despite ongoing talks mediated by other countries. Iran has closed the Strait of Hormuz, a vital maritime trade corridor, and will keep it closed until the US lifts its blockade on Iranian ports. The Iranian Revolutionary Guard Corps (IRGC) has warned that any unauthorized passage through the strait will be considered an act of cooperation with the enemy. The current ceasefire is set to expire on Wednesday unless extended. Disagreements persist over nuclear issues, with Iranian officials rejecting US claims and expressing frustration over the uncertainty of future talks. While Iran's airspace is set to reopen, in-person education remains suspended.

Iran’s “valiant navy” is “ready to inflict new bitter defeats on its enemies”, Supreme Leader Mojtaba Khamenei said on Saturday. Deputy Foreign Minister Saeed Khatibzadeh dismissed Trump’s claims over the uranium and sounded a note of caution with regard to future talks between the two countries. “There is now a certain sense of frustration and uncertainty when it comes to the road ahead. We know that Iranians are very much worried, not only about the shadow of the war, but also about the element of surprise, even during this ceasefire,” Al Jazeera’s Tohid Asadi reported from Tehran. Minister of Education Alireza Kazemi has said the government does not have plans to resume “in-person education” at the moment. The Iranian Ministry of Science announced that in the “third imposed war,” 180 members of the academic community were killed, including 18 female students and one female university professor. The Tasnim News Agency, citing the deputy director of Iran’s Civil Aviation Organisation, said the country’s airspace would be reopened, with flights from east to west established gradually. The aviation authority said Iran will resume international flights on Monday from Mashhad airport in the country’s northeast. Iran is replenishing its missile and drone launchers at a ⁠higher speed than before the war started, Majid Mousavi, the Revolutionary Guard’s Aerospace Force commander, said. ⁠Iran’s ⁠armed forces turned back two tankers attempting ⁠to transit the Strait ⁠of Hormuz after issuing warnings, semi-official Tasnim ‌news agency reported.
