The Israeli military attacked the southern suburbs of Beirut, seen as a stronghold of Lebanese Shiite militia Hezbollah, with at least four airstrikes on Thursday, according to a dpa reporter who witnessed them.

The deaths on Wednesday made it one of the most lethal days for the Israeli military since it invaded Lebanon last month to battle Hezbollah fighters.

The Israeli military pounded Beirut's southern suburbs with airstrikes on Tuesday, mounting one of its heaviest daytime attacks yet on the Hezbollah-controlled area after the defence minister ruled out a ceasefire until Israeli goals were met.
