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.

Israeli airstrikes pounded Beirut's Hezbollah-controlled southern suburbs for a second consecutive day on Wednesday, as Lebanon waited to hear Washington's latest ceasefire proposals after a U.S. official expressed hope a truce could be reached.
