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

The Lebanese army said it is ready to deploy to the country's south after the Israeli army withdraws from the region, as stipulated in the ceasefire agreement signed last year.

Civilians should not yet return to areas that Israel is withdrawing from, and should continue to follow the instructions of the military units until deployment ends, the Lebanese army said. Specialized units will still need to clear areas of mines and suspicious objects left by Israeli forces, the Lebanese army said.

Lebanese military units completed their deployment at several points in the town of Kfar Shuba, Hasbaya, in the eastern sector after the withdrawal of the Israeli troops.

The United Nations Interim Force in Lebanon also said it is ready to support the Lebanese army after Israel withdraws.

Israel is required by the ceasefire to withdraw by Sunday.

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.
