The death toll in a gun and suicide bomb attack on Istanbul’s Ataturk airport has risen to 41, 13 of them foreign nationals, with 239 injured, the Turkish city’s governor says.

Cleaners worked through the morning to sweep up shattered glass, while workers repaired cables and ceiling tiles. Heavily-armed security personnel were patrolling the airport.
Flights had resumed in the early morning, though with many cancellations and delays.
Turkish President Recep Tayyip Erdogan said the attack should serve as a turning point in the global fight against militant groups.
Reports of the attack vary but it appears the attackers opened fire at the entrance where X-ray machines are positioned, sparking an exchange with police. At least two of the attackers ran into the building.
Footage on social media shows one moving through the building as people around him flee. He is shot by police and remains on the ground for about 20 seconds before blowing himself up. All three attackers were killed.
