Israel’s military targeted a senior Hezbollah commander in an airstrike in a Beirut suburb Friday, Israeli officials said, escalating a days-long assault on the group’s communications and logistics infrastructure and shocking an already traumatized nation fearful of an all-out war.

Hezbollah pounded northern Israel with 140 rockets Friday, a day after the militant group’s leader Hassan Nasrallah vowed to retaliate against Israel for a mass bombing attack, the Israeli military and the militant group said.
