British Airways has confirmed that the flight has been diverted to Sofia, Bulgaria.

https://twitter.com/British_Airways/status/754069013785878529 According to the @airlivenet Twitter account, which provides live updates on air traffic, all outbound flights have been cancelled and many - if not all - incoming flights have been diverted. At the time of writing, it is unclear whether a small number of Turkish Airlines flights were able to land at the airport. FlightRadar reports that the last flight out of Istanbul, an Onur Air flight to Elazig, left Ataturk Airport at approximately 10pm UK time. Further international flights are believed to have been grounded, according to unconfirmed reports. Flights operated by British Airways and KLM have both been confirmed as having been diverted, and both airlivenet and FlightRadar are among the Twitter accounts providing real-time updates.
