LONDON — British Airways abruptly canceled all flights to Cairo on Saturday for what it described as security reasons, a day after the British government warned against traveling to some parts of Egypt.
The airline told passengers at their departure gate in London that they could not fly.
“We constantly review our security arrangements at all our airports around the world,” the airline said in a statement, “and have suspended flights to Cairo for seven days as a precaution to allow for further assessment.”
British Airways did not describe the security issue.
The British government released new travel advice for Egypt on Friday, warning against trips to most of the Sinai Peninsula and the area west of the Nile Valley and saying that travelers to Cairo should be cautious, too.
“There’s a heightened risk of terrorism against aviation,” the government said.
