Iran needs guarantees against another US-Israeli attack before it can ensure security in the oil-rich Gulf, Tehran's envoy to the United Nations has said.

The ambassador, Amir Saeid Iravani, addressed a Security Council session on Monday initiated by Bahrain, in which dozens of countries condemned Iran for exerting control over the crucial Strait of Hormuz.

"Lasting stability and security in the Persian Gulf and the wider region can only be achieved through a durable and permanent cessation of aggression against Iran supplemented by credible guarantees of non-recurrence and full respect for the legitimate sovereign rights and interests of Iran," Iravani told the session.

Speaking afterwards to reporters, Iravani complained that countries only criticised Iran, not the naval blockade imposed by the United States.

"But no one from those who have expressed their concern for international navigation dares to refer to or condemn this terrorist act at today's meeting."

Iravani also accused the US and Israel of waging "unwarranted large-scale war of aggression" against Iran, blaming them for escalating tensions and disrupting maritime security in the Strait of Hormuz.

"Since 28 February, the United States and the Israeli regime have waged an unwarranted large-scale war of aggression against Iran," Iravani said, claiming the actions violate the UN Charter and threaten both regional and global stability.

He accused the US of imposing a maritime blockade, including the seizure of Iranian commercial vessels and detention of crews—actions he characterised as illegal and akin to piracy.

"These dangerous, escalating measures violate international law…and amount to acts of aggression," he said.

Iravani said Iran, as a coastal state bordering the Strait of Hormuz, has taken "necessary and practical measures" to ensure safe navigation and prevent the waterway from being used for hostile military purposes.
