Israel’s defense minister has announced a series of raids that he says are targeting “terrorism” in the occupied West Bank, as Palestinian officials warned of a “man-made disaster.”

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.

At least 10 people have been killed in the raids, and more than 40 wounded, according to the Palestinian Health Ministry. Dozens have been arrested, Palestinian officials told the Wafa news agency.
