Here’s the latest.

The cease-fires in Lebanon and Gaza appeared increasingly fragile on Sunday after Israeli forces remained in southern Lebanon beyond the 60-day deadline for both Hezbollah and Israel to withdraw, and Israel said Hamas had violated the terms of the truce in Gaza.

In Lebanon, at least 15 people were killed and more than 80 injured by Israeli forces in southern Lebanon, Lebanese officials said on Sunday, as thousands of Lebanese displaced by the war poured onto roads leading south back to their homes. Lebanon’s Health Ministry said that those killed and injured had been trying to enter their villages along the border when they were attacked by Israeli forces.

The cease-fire agreement, which was signed in November and halted the deadliest war in decades between Israel and Hezbollah, stipulated that both sides withdraw, while the Lebanese Army and U.N. peacekeepers would be deployed in force to secure the area. Negotiators had hoped the cease-fire deal would become permanent, returning a measure of calm to a turbulent region. But as the deadline passed on Sunday, Israeli forces failed to withdraw, stoking fears of a sustained Israeli occupation and renewed hostilities between Israel and Hezbollah.

The Israeli military said in a statement that it had fired “warning shots” after what it described as “suspects” approached their forces. It also said that an unspecified number of people had been arrested and were now being questioned at the scene.
