TEHRAN, Iran (AP) Iran on Tuesday vowed to respond to an airstrike widely attributed to Israel that destroyed Irans Consulate in the Syrian capital of Damascus the previous day and killed 12 people, including two Iranian generals and a member of the Lebanese militant Hezbollah group.

Four Syrian citizens were also killed in the strike, a Syrian official said Tuesday, without providing any details about them. Hezbollah, which has been a key ally of both Syrian President Bashar Assads government and Iran, also pledged punishment and revenge on Israel.

Israel, which has repeatedly targeted Iranian officers in Syria and in Lebanon, did not confirm Mondays attack.

Iran provides money and weapons to Hezbollah, as well as Hamas and other Palestinian militant groups fighting Israel in Gaza. Clashes between Israel and Hezbollah along the Israeli-Lebanese border have increased since the war in Gaza began nearly six months ag o.

Irans Supreme National Security Council, a key decision-making body, met late on Monday and decided on a required response to the strike, Irans state television reported. It said the meeting was chaired by President Ebrahim Raisi but provided no further details.

We will make them regretful about the crime and similar acts, said Supreme Leader Ayatollah Ali Khamenei, who has final say on all state matters in Iran.

The U.S. National Security Council said the United States played no role in the strike in Damascus and did not know of it ahead of time. Americans directly advised Iran of that, a U.S. official said, speaking on condition of anonymity to discuss the matter.

It was not clear if and when Iran would respond, but any retaliation from Tehran would risk a dangerous confrontation with Israel and the U.S.

Later Tuesday, Assad expressed his condolences in a telephone call with Raisi and condemned Israel, Syrian state news agency SANA reported.

The airstrike killed Gen. Mohammad Reza Zahedi, who led the Iranian Revolutionary Guards Quds Force in Lebanon and Syria until 2016, his deputy, Gen Mohammad Hadi Hajriahimi, and five other officers. A member of Hezbollah, Hussein Youssef, also was killed in the attack.
