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.”

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.

In the days since a ceasefire took hold in the Gaza Strip, Israel has launched a major military operation in the occupied West Bank. The operation comes as the international community calls for the ceasefire to lead to an end to further conflict.
