Since October 8, the day after the war broke out in the Gaza Strip, Hamas ally Hezbollah and its arch-foe Israel have exchanged near-daily fire.

The strikes have been largely contained to the border between the two countries -- although Israel has on occasion launched strikes elsewhere in Lebanon.

"Israeli aircraft targeted a former Hezbollah building near Dar Al Amal Hospital," a security source told AFP, adding that Israel "conducted another raid on a warehouse west of Baalbek".

Another security official confirmed the strikes.

The city of Baalbek in the Bekaa valley is a Hezbollah bastion bordering Syria.

On February 26, Israeli strikes targeted Baalbek, some 100 kilometres (62 miles) from the border, killing two Hezbollah members in the deepest such raid into Lebanese territory since the hostilities began.

Since the start of the Israel-Hamas war in October at least 316 people, mainly Hezbollah fighters, and 53 civilians have been killed in Lebanon, according to an AFP tally.

In Israel, at least 10 soldiers and seven civilians have been killed.
