The West Bank city of Jenin was the target of an ongoing Israeli "anti-terror" operation that claimed the lives of at least 10 Palestinians and injured as many as 40 others.

As many as 600 people were held in a hospital overnight, the mayor of the city of Jenin told a Palestinian news agency. The death toll from the two-day operation rose to 10, officials said.

Israel captured the West Bank, Gaza and east Jerusalem in the 1967 Mideast war, and Palestinians want all three territories for their future state. Escalations in one area frequently spill over, raising further concerns that the second and far more difficult phase of the Gaza ceasefire — which has yet to be negotiated — may never come.
