MAYS AL-JABAL, Lebanon — Israeli forces in southern Lebanon on Sunday opened fire on protesters demanding their withdrawal in line with a ceasefire agreement, killing at least 22 and injuring 124, Lebanese health officials reported.

Hours later, the White House said Sunday that Israel and Lebanon had agreed to extend the deadline for Israeli troops to depart southern Lebanon until Feb. 18, after Israel requested more time to withdraw beyond the 60-day deadline stipulated in a ceasefire agreement that halted the Israel-Hezbollah war in late November.

Israel has said that it needs to stay longer because the Lebanese army has not deployed to all areas of southern Lebanon to ensure that Hezbollah does not reestablish its presence in the area. The Lebanese army has said it cannot deploy until Israeli forces withdraw.

There was no immediate comment from the Israeli government, but Lebanese caretaker Prime Minister Najib Mikati confirmed the extension.
