Iran reiterated on Monday its determination to use all available capabilities to respond to the missile attack launched by Israel on October 26.

Iranian Foreign Ministry spokesman Esmail Baghaei said today that Tehran will use all available tools to respond to the attack launched by Israel on it last Saturday, according to Reuters.

On Sunday, Iran informed the United Nations that it reserved the right to respond to the "criminal Israeli aggression," amid ongoing Iranian assurances in this regard.

The Iranian Foreign Ministry explained that Minister Abbas Araghchi informed the UN Secretary-General of this, and called in a letter he addressed to him for an urgent meeting of the UN Security Council.

Earlier, Iranian President Masoud Pezeshkian said, "We will respond appropriately to the Zionist entity's aggression against our lands," amid US warnings to Iran against "the mistake of responding and taking any retaliatory step."

For his part, Iranian Parliament Speaker Mohammad Bagher Qalibaf said, "The Zionist regime's attack on our country has turned into another defeat for this entity," stressing that the response to it "will be inevitable, as our country considers itself to have the right to self-defense according to the United Nations Charter."

Last Saturday morning, the Israeli army announced that it had launched a fighter jet attack on Iran, which in turn said that it had "successfully confronted the Zionist entity's attempts to attack some points in Tehran and the country." The attack resulted in the deaths of 4 soldiers and one civilian, according to official statements.

This came after Iran anticipated the Israeli attack, following its launch of an attack on Israel more than two weeks ago, in response to the assassination of the former head of the political bureau of Hamas, Ismail Haniyeh, in Tehran in late July, and Tel Aviv’s announcement of its assassination of the Secretary-General of the Lebanese Hezbollah, Hassan Nasrallah, in the southern suburbs of Beirut in late September.
