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.

Israel’s military said Thursday it killed two Islamic Jihad militants who were involved in a deadly attack on a bus in the West Bank earlier this month. The Israel Defense Forces said its troops killed the militants in the village of Burqin amid an exchange of fire after the militants had barricaded themselves in a building.
