The UK government has lifted the laptop ban on some flights from Turkish airports.
The ban on larger mobile devices, which has been enforced on flights to the UK from six countries since March, has been removed for flights from Istanbul Sabiha Gokcen airport.
It has also been lifted on some flights to the UK from Istanbul's Ataturk airport and Izmir. But the changes only apply to services operated by Turkish Airlines and the low-cost carrier Pegasus.
The ban remains in place on flights from other Turkish airports, as well as services to the UK from Egypt, Saudi Arabia, Jordan, Lebanon and Tunisia.
The Department for Transport said in a statement: “After working with the aviation industry and international partners to introduce tough additional security measures, the UK government has begun lifting these restrictions on some UK-bound flights.
“Restrictions remain in place at other airports and will be lifted on a case-by-case basis once the UK government has verified that airlines have put in place alternative security measures, and that it is safe and proportionate to do so.”
The US laptop ban on flights from the Middle East and North Africa ended last week after airports in the region met new security requirements.
