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.

Dozens of people were killed or wounded after an outbreak of violence in the West Bank that Israeli military officials called a counterterrorism operation.

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.”

The Israeli military killed at least seven Palestinians in the occupied West Bank on Tuesday as the prime minister announced the start of a “large-scale military operation” in the restive city of Jenin.

U.S. Secretary of State Marco Rubio spoke with Israeli Prime Minister Benjamin Netanyahu on Wednesday to reiterate Washington's support for its ally, and the two also discussed Iran and Israeli hostages in Gaza, the State Department said.

The Israeli military says its soldiers killed an alleged militant in Gaza whom it said posed a threat to its forces
