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.

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.

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.
