A U.S. backed ceasefire agreement between Lebanon and Israel will remain in effect until the middle of next month, the White House announced Sunday.

The U.S. said on Sunday that the agreement between Lebanon and Israel would remain in effect until Feb. 18, after Israel said on Friday it would keep troops in the south beyond the Sunday deadline set out in a U.

Thirteen-year-old Zakariya Barbakh had spent most of his life shuffling between hospitals across Gaza, the occupied West Bank and Israel.

The first week of the latest ceasefire between Israel and the Hamas militant group is complete. Hamas has begun to release hostages and Israel has freed nearly 300 Palestinian prisoners. But the deal has hit its first major complication.

The fragility of the truce between Israel and Hamas was laid bare on Saturday, after Israel accused Hamas of withholding a hostage, prompting a halt in the movement of Gazan civilians back to their homes in the north.

Prime Minister Sir Keir Starmer has paid tribute to US President Donald Trump for his "role in securing the landmark ceasefire and hostages deal in Gaza" during a call between the two leaders.

Hamas released four Israeli hostages in Gaza early Saturday in exchange for 200 Palestinian prisoners to be released later in the day. It was the second release to occur as part of the ceasefire agreement that began last weekend. Israel followed with the release of 200 Palestinian prisoners.

The U.S. government said on Saturday it was "critical" that implementation of the Gaza ceasefire continues, after four Israeli soldiers were freed by Palestinian Hamas militants in exchange for 200 Palestinian prisoners.

The corpses keep coming every day, sometimes dozens at a time brought to morgues in the Palestinian enclave, after being pried from under 15 months of rubble and pulled from battle zones long too dangerous for search-and-rescue teams to reach.

For a second day, Lebanese were defying Israeli warnings and attempting to reach southern border towns that remained occupied by Israeli troops. At least two people were injured, officials said.
