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.

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.
