British Airways cancelled flights between London's Heathrow Airport and Dubai and Doha on Sunday following US strikes on Iran and fears that the situation in the Middle East could deteriorate.
"As a result of recent events, we have adjusted our flight schedule to ensure the safety of our customers and crew," a BA spokesperson said, confirming that outgoing and incoming flights between Heathrow and Dubai or Doha were cancelled.
A British Airways flight from London Heathrow to Dubai was diverted to Zurich on Saturday night, according to the tracking website Flightradar24.
The BA website showed no flights available for Sunday or Monday when AFP checked for those routes, but flights were still available from Tuesday onward.
BA did not confirm when the flights would resume, but said it would keep the situation under review.
