Three key U.S. allies said over the past week that they would recognize a Palestinian state, and others said they were considering doing the same — a major shift that leaves Israel increasingly isolated amid mounting international concerns over the humanitarian crisis in Gaza.

Prime Minister Mark Carney says Canada will recognize a Palestinian state in September if the West Bank's governing body agrees to make certain commitments.

If France and the UK do formally recognise Palestinian statehood, the US - a strong ally of Israel - will be the only permanent member of the UN Security Council not to do so.
