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.

In the days since a fragile ceasefire took hold in the Gaza Strip, Israel has launched a major military operation in the occupied West Bank and suspected Jewish settlers have rampaged through two Palestinian towns.

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.
