Middle East updates: Israel-Lebanon ceasefire extended to Feb. 18

At least 21 Palestinians were injured, 11 severely, after dozens of Israeli civilians, some of whom were masked, arrived at the area of Al Funduq, in the West Bank, and "instigated riots, set property on fire and caused damage," according to the Israel Defense Forces.

Three homes were burned down and five cars were torched as well, the IDF said.

The civilians hurled rocks and attacked the security forces dispatched to the scene, according to the IDF.

Israeli Minister of Defense Israel Katz, despite freeing settlers who committed the same types of crimes, said he condemns the violence.

More than 1,500 trucks with humanitarian aid have entered the Gaza Strip in the first two days of the Israel-Hamas ceasefire, according to the United Nations Office for the Coordination of Humanitarian Affairs (OCHA).

That includes more than 630 trucks on Sunday and 915 trucks on Monday, according to OCHA. Of the ones that crossed into Gaza on Sunday, OCHA said at least 300 trucks went to the north, which the U.N. has warned is facing imminent famine.

OCHA cited “information received through engagement with Israeli authorities and the guarantors for the ceasefire agreement.”

“There is no time to lose,” the U.N.’s aid chief, Tom Fletcher, said in a statement Monday. “After 15 months of relentless war, the humanitarian needs are staggering.”

Israel Defense Forces and Israel Border Police Forces were dispatched to Al Funduq in the West Bank after reports of rioting in the area, the IDF said on Monday.

The alleged incident occurred shortly after Israel's defense minister released all settlers being detained under administrative detention orders, though it cannot be certain that any of those settlers were involved in the reported riots. ABC News was able to confirm that fires had ignited in that location.

Shortly thereafter, the IDF confirmed that it had successfully dispersed rioters.

There have been no confirmed reports as to the extent of the damage or any injuries. Israeli officials are expected to conduct a formal inquiry in the area tonight.

Israeli forces recovered the body of Oron Shaul, an Israel Defense Forces soldier who was killed in 2014, Prime Minister Benjamin Netanyahu and the IDF announced Monday.

Shaul was killed during a battle in Gaza on July 30, 2014, and his body had been held by Hamas for the past 10 years, the IDF said.

"The recovery of Staff Sergeant, Oron Shaul’s body, was made possible due to a decade-long ongoing intelligence effort, which intensified during the war," the IDF wrote in a statement about the operation on Monday.

Netanyahu spoke with Oron Shaul's mother, Zehava Shaul, after the operation was successfully completed, a statement from his office said.
