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.

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.”

As Israel withdraws some of its troops from Gaza during a cease-fire there, it has turned attention to another Palestinian territory — in particular a city with a history of militant activity.

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.

Israeli operations in the West Bank have killed at least 12 Palestinians since Tuesday and could threaten the newly agreed ceasefire in Gaza, United Nations Human Rights office spokesperson Thameen Al-Kheetan said on Friday.

The action came a day after President Donald Trump said he will lift sanctions on ultranationalist Israeli settlers who attacked Palestinian villages.

Prime Minister Benjamin Netanyahu said the assault on Jenin would be “extensive and significant,” as the military erected new checkpoints across the West Bank.
