Israel leveled a building in Lebanon on Sunday after Iran's massive drone and missile attack, but it was unclear if the events were connected or had been planned ahead of time.
Israel's attack targeted a building near the Syrian border used by Lebanon's Iran-backed Hezbollah group, according to the AFP news agency.
The group said that there were no casualties.
Lebanon's state-run National News Agency said the building in the village of Nabi Sheet was destroyed in the attack.
"Fighter jets struck a significant Hezbollah weapons manufacturing site," the Israeli Army said in a statement.
Hezbollah said it launched rockets towards the Israeli-controlled Golan Heights during the Iranian attack on Israel.
Israeli Prime Minister Benjamin Netanyahu said Sunday that Israel will be victorious after Iran's unprecedented attack on the Jewish State, and in warnings just before the barrage.
