A plane carrying American pro-democracy campaigners and other activists left Egypt on Thursday after a travel ban was lifted, an airport official said, a move that is likely to defuse the deepest row between Washington and Cairo in decades.

They have left, the airport official told Reuters, without giving further details. A U.S. military plane had been sent to Egypt to take them, airport officials had said earlier.
