Beirut. The Lebanese Hezbollah group says it has launched over 200 rockets at several military bases in Israel in retaliation for a strike that killed one of its senior commanders.

The attack by the Iran-backed militant group on Thursday was one of the largest in the monthslong conflict along the Lebanon-Israel border, with tensions boiling in recent weeks.

The Israeli military said "numerous projectiles and suspicious aerial targets" had entered its territory from Lebanon, many of which it said were intercepted. There were no immediate reports of casualties.

It acknowledged on Wednesday that it had killed Mohammad Naameh Nasser, who headed one of Hezbollah's three regional divisions in southern Lebanon, a day earlier.

Hours later, Hezbollah launched scores of Katyusha rockets and Falaq rockets with heavy warheads into northern Israel and the occupied Syrian Golan Heights. It launched more rockets on Thursday and said it had also sent exploding drones into several bases.

The US and France are continuing to scramble to prevent the skirmishes from spiraling into an all-out war, which they fear could spill over across the region.

The relatively low-level conflict erupted shortly after the outbreak of the war in Gaza. Hezbollah says it is striking Israel in solidarity with Hamas, another Iran-allied group that ignited the war in Gaza with its Oct. 7 attack into southern Israel.

The fighting has displaced tens of thousands of people on both sides of the border. In northern Israel, 16 soldiers and 11 civilians have been killed. In Lebanon, more than 450 people -- mostly fighters but also dozens of civilians -- have been killed.
