Nigerian airline Dana Air has had its licence suspended after a crash killed all 153 people on board one of its planes as well as others on the ground.
An investigation was launched after the local flight from Abuja plunged into a busy suburb of Lagos on Sunday.
The focus is now on whether the plane was too old to fly and whether Dana Air and the Civil Aviation Authority carried out all the necessary inspections before take-off.
