The base is in Qatar, but Esmail Baqai says Iran’s actions were an “act of self-defence”.

“Iran remains fully committed to its good-neighbourliness policy with respect to the State of Qatar and other neighbouring countries,” Baghaei posted on X.

“We resolve not to let US/Israeli criminal aggressions and malign policies against Iran create division between us and the brotherly countries of the region.”

Qatar has sent a letter to the UN secretary general to condemn the Iranian attack targeting the US-run Al-Udeid air base on Monday.

In a statement, Qatar’s Ministry of Foreign Affairs says the letter describes the attack as an "extremely dangerous escalation that represents a flagrant violation" of Qatar's "sovereignty and territorial integrity".

The letter also says the Iranian Revolutionary Guard Corps' missile attack posed "a direct threat to regional peace and security".

"The State of Qatar stressed that it reserves the right to respond directly in a manner equivalent with the nature and scale of this blatant aggression and in accordance with the Charter and international law," the statement adds.

Qatar also says it has summoned the Iranian ambassador.

On Monday, the foreign ministry has also condemned the missile attack on the US base, which the country said was fully intercepted.

Iran's General Staff of the Armed Forces Abdolrahim Mousavi has denied firing any missiles towards Israel in the last few hours, according to Iranian state media.

This comes after earlier denials in state media, which said reports that Iran had attacked Israel after the start of the ceasefire were false.

The chief of the general staff of the Israel Defense Forces (IDF) says the military will "respond with force" to what it calls Iran's "severe violation".

"In light of the severe violation of the ceasefire carried out by the Iranian regime, we will respond with force," Eyal Zamir is quoted as saying in a post on X by the IDF.

As we've reported, Israel said it had detected missile launches from Iran. Iranian state media has denied the accusation that it fired a missile at Israel after the ceasefire.

Iran's Supreme National Security Council has released a statement about "imposing the halt of the war" on Israel and its "terrorist supporters".

The Council warns that "any further aggression will be met with a decisive, firm, and timely response by Iran".

In the statement, the Council praises the Iranian people for their "awareness, resilience and unity", saying the "enemy’s defeat" is down to Iranians’ "firm resolve, strategic patience, and refusal to accept humiliation or one-sided compromise".

The statement also commends Iran and its forces for delivering "decisive and calculated blows" in retaliation for attacks on Iran.
