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

At least 10 Palestinians were killed and 40 injured as Israel continues a large operation in Jenin, turning its focus to the West Bank.

Israel launched a "significant" operation to "eradicate terrorism in Jenin," Prime Minister Benjamin Netanyahu said in a statement Wednesday.

"This is another step towards achieving the goal we set -- strengthening security in Judea and Samaria. We are acting systematically and resolutely against the Iranian axis wherever it extends its arms -- in Gaza, Lebanon, Syria, Yemen and Judea and Samaria -- and with our hands still outstretched," Netanyahu said in a statement.

At least four people were injured in a stabbing attack in Tel Aviv on Tuesday, Magen David Adom, Israel's emergency services organization, said in a release.

Two men, ages 28 and 24, are being treated with upper-body stab wounds and are in moderate condition. Two other patients, ages 24 and 59, are in mild condition, the MDA said.

The injured are being taken to Ichilov Hospital.

The stabbing occurred on Nahalat Binyamin Street in Tel Aviv, the Israeli Police Spokesperson's Unit said. The attacker, a 28-year-old "foreign national," has been killed by police, the spokesperson's unit added.

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.”
