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.”

The city of Jenin, a Palestinian militant stronghold in the Israeli-occupied West Bank, has become a new front for Israel days after it reached a ceasefire deal with Hamas that suspended a 15-month-old war in Gaza.

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.
