Israel has dealt Hezbollah heavy blows since launching its offensive in late September, escalating the conflict that had rumbled on in parallel to the Gaza war for a year. Hezbollah has kept up rocket fire into Israel and its fighters have been battling Israeli troops on the ground in the south.

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.
