Hezbollah and Israel launched fresh attacks across the border as Hassan Nasrallah spoke for the first time since the mass bombing of devices in Lebanon and Syria that he described as a “severe blow” — and for which he promised to retaliate.

The leader of Hezbollah vowed Thursday to keep up daily strikes on Israel despite this week’s deadly sabotage of its members’ communication devices, and said Israelis displaced from homes near the Lebanon border because of the fighting would not be able to return until the war in Gaza ends.
