"The IDF (Israeli military) is currently conducting extensive strikes in southern Lebanon and the Beqaa area," the military said in a statement.

It said it was striking Hezbollah targets and weapons storage facilities.

It also said that some 40 projectiles had crossed into northern Israel from Lebanon, setting off warning sirens in the area.

"Several projectiles were intercepted," the military said.

"The Hezbollah terrorist organisation continues to launch projectiles toward civilian areas and facilities on the Israeli home front."
