US Ambassador to Israel Mike Huckabee has described Israeli settler violence in the occupied West Bank as meeting the definition of terrorism, in a rare public rebuke from a senior American official. His comments follow a days-long siege of the home of a Palestinian-American family by Israeli settlers in Qusra, a Palestinian village in the northern West Bank. The remarks are notable given Washington's traditionally close alignment with Israel, and signal growing US concern over escalating settler attacks on Palestinian civilians.
