+ Iran's ambassador in Pakistan, Reza Amiri Moghadam, said on Tuesday that Pakistan's efforts to stop the war are "approaching a critical, sensitive" period.

+ But Moghadam sounded less enthusiastic in an interview with state-run media, where he set out the country's position: "A complete cessation of the war is Tehran's maximum demand in the process of peace diplomacy," adding, "with a guarantee of nonrepetition of aggression." Moghadam also warned Gulf countries, which he did not name, to "pay attention to their conditions and relations with Iran." He warned: "Know that sooner or later America will leave this region by accepting defeat and you will stay." Earlier, Iranian state media said the government rejected U.S. demands, transferred by intermediaries, and presented a plan of its own. Iran's 10-point proposal included a guarantee that Iran would not be attacked again, an end to Israeli strikes against the Iranian-backed Hezbollah in Lebanon and removal of sanctions in exchange for the reopening of the Strait of Hormuz, with Iran imposing a $2 million fee for every ship moving through the key waterway, according to The New York Times. Israeli Prime Minister Benjamin Netanyahu says Israel is stepping up its attacks against Iran, hitting railways and bridges he says are used to transport weapons and military equipment and regime operatives. He says the strikes weren't aimed against civilians but to crush the regime. Middle East conflict Iran rejects a U.S. ceasefire plan as Trump again threatens to bomb its infrastructure Israel had issued a warning to Iranians to avoid travel by train and to stay away from railway tracks. The warning was posted on social media but the internet has been largely shut down across the country. Earlier, Israel's military said it attacked one of the "few remaining" petrochemical facilities producing ballistic missile and explosive material in Shiraz, in southern Iran. It also said it struck a ballistic missile site in northwestern Iran and infrastructure across the country.

Saudi Arabia's Defense Ministry said it was assessing damage on its energy facility caused by falling debris from dozens of ballistic missiles and drones intercepted by its air defense systems on Tuesday. The United Arab Emirates said its air defense systems engaged with incoming missiles and drones on Tuesday, while Kuwait's army said it shot down 17 "hostile drones" in the past 24 hours. Russia and China vetoed a United Nations Security Council resolution put forth by Bahrain that would have demanded that Iran stop all attacks on commercial vessels in the Strait of Hormuz. Bahrain's foreign minister says Iran has no right to close the Strait of Hormuz — which has impacts on food and energy security around the globe. He criticized the council for failing to back his resolution. U.S. Ambassador to the U.N. Mike Waltz echoed that, saying "No one should tolerate that they are holding the global economy at gunpoint, but today, Russia and China did tolerate it." The resolution would have called on Iran to stop all attacks on civilian infrastructure. The draft did not mention U.S. and Israeli attacks or threats to strike Iranian bridges, power plants and other civilian infrastructure. Russia argues that the path to de-escalation starts with the U.S. halting its attacks.
