The sudden expansion of Israeli security operations in the West Bank has killed at least 10 people and follows the start of the delicate ceasefire process in Gaza, by which Israeli hostages are released in stages and will also see the gradual withdrawal of Israeli forces.

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.
