Israel's military said in a statement early on Monday it launched multiple air and artillery strikes overnight on what it said were Hezbollah military targets in Lebanon.
The strikes came after the Iranian-backed militant group said on Sunday it had launched a drone attack on Mount Hermon in the Israeli-occupied Syrian Golan Heights.
Israel has key surveillance, espionage and air defense installations on Mount Hermon where it overlooks the Syrian capital.
Hezbollah said this was its first such bombing since it began trading fire with Israel on Oct. 8, a day after Hamas attacked southern Israel, sparking the Gaza war. Hezbollah says it would halt operations only when the war ends.
Although it had hit other areas in the occupied Syrian Golan Heights repeatedly, Hezbollah said it was the first time to hit the military target that is at the highest elevation in the Israeli-controlled territory.
