A passenger on a Turkish Airlines flight had to be subdued after he began screaming.
The unnamed man was seated in business class on board the Boeing 737-900 when he started flailing at an oxygen mask box and the cabin window.
Associated Press photographer Hussein Malla was on the flight from Istanbul to Khartoum on Friday and says several passengers stopped the man.
It took flight attendants 15 minutes to calm the man down and take him to the back of the plane to be seated.
But after about two hours, the pilots announced the plane was returning to Istanbul.
