BEIRUT (AP) Israel killed a top Hezbollah commander Tuesday as part of a two-day bombing campaign that has left more than 560 people dead and prompted thousands in southern Lebanon to seek refuge from the widening conflict.

With the two sides on the brink of all-out war, Hezbollah launched dozens of rockets into Israel on Tuesday, targeting an explosives factory and sending families into bomb shelters.

Families that fled southern Lebanon flocked to Beirut and the coastal city of Sidon, sleeping in schools turned into shelters, as well as in cars, parks and along the beach. Some sought to leave the country, causing a traffic jam at the border with Syria .

Issa Baydoun fled the village of Shihine when it was bombed and drove to Beirut with his extended family. They slept in vehicles on the side of the road because the shelters were full.

We struggled a lot on the road just to get here, said Baydoun, who rejected Israels contention that it hit only military targets. We evacuated our homes because Israel is targeting civilians and attacking them.

Volunteers cooked meals for displaced families at an empty Beirut gas station that first became a hub for relief after a devastating port explosion in 2020.

Israel said late Tuesday that fighter jets carried out extensive strikes on Hezbollah weapons and rocket launchers across southern Lebanon and in the Bekaa region to the north.

Asked about the duration of Israels operations in Lebanon, military spokesman Rear Adm. Daniel Hagari said at a news conference that it aims to keep them as short as possible, thats why were attacking with great force. At the same time, we must be prepared for it to take longer.

Tensions between Israel and the Lebanese militant group Hezbollah have steadily escalated over the last 11 months. Hezbollah has been firing rockets, missiles and drones into northern Israel in solidarity with Palestinians in Gaza and its ally Hamas, a fellow Iran-backed militant group.

Israel has responded with increasingly heavy airstrikes and the targeted killing of Hezbollah commanders while threatening a wider operation.
