An Israeli strike on a four-storey residential building has killed at ​least four people and wounded six others in the ‌eastern Lebanese city of Baalbek, state news agency NNA said.

Rescue teams were also working to pull families from beneath the rubble.

The strike was ​part of a sharp escalation in fighting along the Lebanese-Israeli border ​since Monday, after Hezbollah fired drones and missiles at ⁠Israel.

Since then, the Iran-aligned group has launched more rockets and ​Israel has carried out waves of air strikes across Lebanon and ​sent troops into the south.

Hezbollah said ​on Wednesday it fired rockets at a gathering of ‌Israeli ⁠forces near the frontier in response to Israeli strikes on Lebanon.

Israel also warned residents in 16 Lebanese villages to evacuate, saying ⁠Hezbollah activity was forcing it to act.

Lebanon’s health ministry ⁠said ​on Tuesday that Israeli strikes had ​killed at least 50 people and wounded 335 since the latest escalation began.
