Iran's supreme leader released a statement on Tuesday saying those who bombed his country's embassy compound in Syria will "regret" the crime. Ayatollah Ali Khamenei blamed Israel's "Zionist regime."

Israel has not claimed responsibility.

The compound in Damascus was struck on Monday, and a consular building was destroyed. Iran's state-run media says 13 people were killed, including a senior commander of its elite Quds Force and Syrian citizens.

Syrian Prime Minister Hussein Arnous visited the embassy and also accused Israel, which he calls "a country that violates and does not understand the law."

Iranian Ambassador to Syria Hossein Akbari said, "There is, of course, an international responsibility toward this crime and, naturally, there will be an Iranian response." He called for the United Nations Security Council to take up the matter.

Members of the council held an emergency meeting on Tuesday. Russian Ambassador Vassily Nebenzia questioned why US officials had not gathered any intelligence on the attack.

Deputy US Ambassador Robert Wood denied that his country was involved. He said, "One thing is clear: Iran and its proxy and partner groups need to avoid escalating tensions in the region."

Wood also accused Iran and Syria of backing groups that have plotted attacks on US and Israeli personnel and facilities.
