“All accusations (of involvement by this group) are false.”
Before reports of the impact of the airstrikes were available, Hezbollah claimed responsibility for four attacks, including one on the Hermon Brigade's military headquarters on the slopes of Mount Hermon, about two miles from the football field where the blasts occurred.
The strikes followed Israeli airstrikes in Lebanon that killed four militants.
Israeli Prime Minister Benjamin Netanyahu, who is visiting the United States, has brought forward his return home. He was briefed by his aides on Saturday.
“Hezbollah will pay a heavy price, a price it has never paid before,” Netanyahu told leaders of Israel's Druze community in a phone call, according to a statement from his office.
“We are facing an all-out war,” Foreign Minister Israel Katz told Israel's Channel 12 news station.
Israeli President Isaac Herzog called the incident a “horrible and shocking catastrophe” and said Israel would “resolutely defend its people and its sovereignty.”
The Lebanese government also issued a rare statement in response, saying it “condemns all acts of violence and aggression against civilians and calls for an immediate cessation of hostilities on all fronts. Targeting civilians is a blatant violation of international law and goes against humanitarian principles.”

Majdal Shams is one of the four villages in the Golan Heights. There are about 25,000 Druze living there.
When the Golan Heights were annexed from Syria in 1981, they were offered Israeli citizenship, but only a few accepted it.
Most remain loyal to Syria. Druze in the Golan can still study and work in Israel, but only those with citizenship can vote and military service is mandatory.
Most of the international community does not recognize Israel's annexation of the area.
The Druze are an Arabic-speaking ethnic group, most of whom live in Lebanon, Syria, and northern Israel. In Israel, they have full citizenship and make up about 1.5% of the population.
The Israeli Druze community, like other citizens, undergoes mandatory military service and is the largest non-Jewish group serving in the IDF.
