Palestinian President Mahmoud Abbas has been blocked from attending the UN General Assembly session in New York next month, after he and 80 other Palestinian officials had their visas revoked, the US State Department has said.
US Secretary of State Marco Rubio blamed them for undermining peace efforts and for seeking "the unilateral recognition of a conjectural Palestinian state".
The decision, welcomed by Israel, is unusual as the US is expected to facilitate travel for officials of all countries wishing to visit the UN headquarters.
The ban comes as France leads international efforts to recognise a state of Palestine at the session - a move Donald Trump's administration has opposed.
