The war between Israel and Hezbollah is continuing to escalate, with hundreds of people killed in Lebanon and hundreds of thousands more forced from their homes since the beginning of the month.

Much of Israel's air and ground operations have focused on the south of Lebanon. The BBC spent Wednesday with rescue workers in the city of Nabatieh, witnessing the pace and scale of bombings there - a day before the city and much of the land around it was included in a new set of sweeping Israeli evacuation orders.

The late afternoon silence in Nabatieh was broken by the whistle of a missile and the boom of an explosion in the valley beneath the Nabih Berri government hospital.

Medics and displaced people rushed to the hillside to peer beneath as ambulances raced to the scene with their sirens blaring.

"See how big it is," one man said. "It lit up the sky."
