Israel vows to hit Hezbollah after rocket kills 12 on football field

Thousands of mourners attended funeral ceremonies on Sunday for the 12 children and teenagers killed by a rocket strike in the Israeli-occupied Golan Heights as Israel vowed swift retaliation against the Hezbollah militia in Lebanon.

Hezbollah denied responsibility for the attack on Majdal Shams, the deadliest in Israel or Israeli-annexed territory since Palestinian militant group Hamas' Oct. 7 assault sparked the war in Gaza. That conflict has spread to several fronts and now risks spilling into a wider regional conflict.

Israeli jets hit targets in southern Lebanon overnight but a stronger response was expected following a meeting of the security cabinet at 6 p.m. (1500 GMT). Prime Minister Benjamin Netanyahu returned from a visit to the United States.

U.S. Secretary of State Antony Blinken said there was every indication that the rocket, which hit a sports field where children were playing football, had been fired by Hezbollah and said Washington stood by Israel's right to defend itself.

But he said the U.S. did not want a further escalation of the conflict, which has seen daily exchanges of fire between the Israeli military and Hezbollah along the border.

Britain expressed concern at further escalation while Egypt said the attack could spill "into a comprehensive regional war."

On the ground, families gathered for funerals in the Druze village of Majdal Shams in the Golan Heights, territory captured from Syria by Israel in the 1967 Middle East war and annexed in a move not recognised by most countries.

Members of the Druze faith, which is related to Islam, Christianity and Judaism, make up more than half the 40,000-strong population of the Golan Heights. Large crowds of mourners, many in traditional high white and red Druze
