Israel-Gaza updates: Police killed in border shooting, authorities say

Five people were killed after Israeli strikes hit a location "in the humanitarian area in Deir al-Balah," near the Al-Aqsa hospital, according to the Gaza Ministry of Health and Israeli Defense Forces.

Israeli forces were conducting a "targeted strike on terrorists who operated in a Command and Control Center," used by Hamas and the Islamic Jihad there, the IDF said in the release.

Six people were killed in the Tubas and Far'a neighborhoods in the West Bank after an Israeli operation was carried out overnight, the Israel Defense Forces and Palestinian Ministry of Health said in statements Thursday.

The IDF called the operation in Tubas and Far'a a "counterterrorism operation."

Since the IDF operation began last week, 39 people have been killed and about 145 people have been injured in the West Bank, the Palestinian Ministry of Health said.

Israeli Defense Minister Yoav Gallant said the government must "remain focused" on the "resurgence of terrorism in the West Bank," in remarks Thursday.

The polio vaccination campaign in Gaza is making "great progress," according to United Nations Relief and Works Agency for Palestine Refugees in the Near East Commissioner-General Philippe Lazzarini.

The World Health Organization said the next phase of the campaign begins Thursday in southern Gaza targeting an estimated 340,000 children under 10.

The Palestinian Ministry of Health said that at least 39 people have been killed and 145 injured in the West Bank over the past week, amid Israel's major -- and still unfolding -- operation there.

Those casualties bring the total number of deaths in the West Bank since Oct. 7 to at least 691, with an estimated 5,700 injured.
