LONDON — British Airways said on Friday that it was resuming flights to Cairo, nearly a week after abruptly canceling services to the Egyptian capital over security concerns.

The airline said in an emailed statement that it had made the decision after “a thorough assessment of the security arrangements.”

“The safety and security of our customers and crew is always our priority,” it added, “and we would never operate an aircraft unless it was safe to do so.”

British Airways had suspended its sole daily flight from Heathrow Airport, London’s main hub, on Saturday, after the British government warned of a heightened risk of terrorist attacks against planes over Egypt, and advised against traveling to the country.
