Iran's National Security Council Secretary Ali Larijani declared on Tuesday, March 2, that Tehran "will not negotiate with the United States," denying reports of diplomatic outreach.
Meanwhile, overnight U.S.-Israeli strikes continued across Iran, and the first reports emerged that three American service members have been killed and five seriously wounded.
"We will not negotiate with the United States," Larijani wrote on X, rejecting a Wall Street Journal report that he had sought to restart talks through Oman.
The conflict, now entering its third day, has expanded to include 1,311 Iranian missiles and drones fired at regional targets over 48 hours, overnight strikes on Tehran, Karaj, Isfahan, Yazd, and Khuzestan, and the first confirmed American military fatalities.
Larijani launched a 'blistering attack' on Trump, accusing him of dragging the region into chaos through "delusional fantasies" and sacrificing American soldiers for Israel's ambitions.
"Trump plunged the region into chaos with 'delusional fantasies' and is now worried about more American casualties," Larijani wrote in Farsi on X.
"With his delusional actions, he turned his self-made slogan of 'America First' into 'Israel First' and sacrificed American soldiers for Israel's power-seeking," he added.
"Iran's armed forces did not initiate the aggression," Larijani said, adding that, "Today the Iranian nation is defending itself."
Iran launched a total of 1,311 missiles and drones at targets across Arab countries in two days, according to data compiled by Anadolu Agency (AA) from official sources.
Overnight strikes continued to hit Gulf countries:
In Bahrain, a missile's shrapnel struck a foreign vessel under maintenance at a shipyard near Salman Port in Manama, killing one Asian worker and seriously wounding two others.
A point near the U.S. base in Manama was also targeted.
In the UAE, Dubai was targeted in evening strikes with air defense systems firing and explosions heard in the sky.
No official casualty figures were released.
Kuwait's military said it intercepted "hostile air targets" detected over central areas of the country in the early morning hours.
No casualties were reported. Kuwait's Commerce Minister banned all food product exports to maintain domestic market stability.
In Iraq, two drones targeted a U.S. logistics base near Baghdad International Airport. Air defenses intercepted one drone; the other struck Iraq's Special Operations Command headquarters, causing damage but no casualties.
The Hashd al-Shaabi said four of its members were killed and 11 were wounded in a "U.S.-Israeli airstrike" on its headquarters in Anbar province.
Foreign Minister Abbas Araghchi published a letter to UN Secretary-General Antonio Guterres and Security Council members, accusing the U.S. and Israel of violating international law and the 1973 Convention on the Prevention and Punishment of Crimes Against Internationally Protected Persons.
"This act gives rise to the international responsibility of the states involved. It also entails the individual criminal responsibility of the U.S. President, the Israeli Prime Minister, and all persons involved in the planning, ordering, approval, commission, or any form of aiding and abetting of this criminal act," Araghchi wrote.
He said Iran reserves its right to self-defense under Article 51 of the UN Charter and called on Guterres to take "immediate, concrete and effective steps."
