The United Nations Interim Force in Lebanon (UNIFIL) said Sunday that it is "very concerned about reports of Lebanese civilians returning to villages where" Israeli forces are still present and of "casualties due to Israeli fire."

The Israeli army on Sunday claimed that Hezbollah had asked residents to return to the southern border villages in defiance of Israel's warnings, after Israeli gunfire killed at least 11 Lebanese citizens and wounded 83 others.

The Israeli army said in a statement that its troops fired warning shots to “remove threats in a number of areas where suspects were identified approaching.”

The Lebanese Army said Sunday that Israeli fire killed one of its soldiers in the south of the country, where hundreds of residents were trying to return to their homes on the deadline for Israel to withdraw.

United Nations Special Coordinator for Lebanon Jeanine Hennis-Plasschaert and UNIFIL Head of Mission and Force Commander Lt. Gen. Aroldo Lázaro on Sunday issued a statement commenting on the situation in south Lebanon after Israel refrained from withdrawing its troops prior to the January 27 deadline.

French President Emmanuel Macron has called on all parties to the Lebanon ceasefire to honor their commitments as soon as possible, his office said, as Lebanon accused Israel of "procrastination."

The Lebanese army said Sunday that it was escorting civilians into some southern Lebanese border towns and called on residents to follow military instructions to ensure their safety, as Israeli gunfire killed at least three of the returnees and wounded 44 others.

President Joseph Aoun said in a statement addressing the people of southern Lebanon on Sunday that “Lebanon’s sovereignty and territorial integrity are non-negotiable" and that he is "following up on this issue at the highest levels to ensure your rights and dignity.”

"This is a day of victory for Lebanon and the Lebanese -- a victory of right, sovereignty and national unity. As I share you this great joy, I call on you to show restraint and trust the Lebanese Armed Forces, which are keen on protecting our sovereignty and security and securing your safe return to your homes and towns," Aoun said in a statement.

The United Arab Emirates had announced that it reopened its embassy in Lebanon, state media reported, years after it was shut down in solidarity with Saudi Arabia.

The Trump administration said it wants to give Israel a little more time to pull its troops out of Lebanon, just two days before a withdrawal deadline under a ceasefire deal with Hezbollah.

“A short, temporary ceasefire extension is urgently needed” in Lebanon, U.S. National Security Council spokesperson Brian Hughes said in a statement Friday. Israel was supposed to withdraw all its forces from southern Lebanon by Sunday. The 60-day ceasefire deal in late November halted the Israel-Hezbollah war.

The Lebanese Army on Saturday said it has been unable to deploy its forces throughout southern Lebanon as laid out in a ceasefire agreement that halted the Israel-Hezbollah war because of Israel’s “procrastination in withdrawal” from the area.

Under the deal reached in November, Israel is supposed to complete its withdrawal from Lebanon by Sunday, after which the Lebanese armed forces would patrol the buffer zone in southern Lebanon alongside U.N. peacekeepers to prevent Hezbollah from reestablishing a military presence there.
