The New York Times cited four unnamed Israeli officials as acknowledging Israel had carried out the attack. Iran's U.N. mission described the strike as a "flagrant violation of the United Nations Charter, international law, and the foundational principle of the inviolability of diplomatic and consular premises." Saying the strike was "a significant threat to regional peace and security," the Iranian mission urged the U.N. Security Council to condemn the attack and said Tehran reserved the right "to take a decisive response." Hezbollah, the Lebanese group seen as Iran's most powerful armed proxy in the region, vowed to retaliate. "This crime will not pass without the enemy receiving punishment and revenge," the group said in a statement.
