Four people were wounded by Israeli air strikes near Lebanon’s eastern city of Baalbek overnight, one of which hit a two-storey building, an AFP correspondent said.

Israel and Hamas ally Hezbollah have been exchanging near-daily cross-border fire since the Gaza conflict erupted in October.

But fears have surged of an all-out conflict in past weeks, with Israel launching air strikes deeper into Lebanese territory, targeting the Baalbek area — a Hezbollah stronghold — several times.

The Israeli military said in a statement fighter jets “struck a Hezbollah manufacturing site containing weapons in the area of Baalbek”.
