Airspace over Lagos was temporarily suspended on Monday after a fire broke out at Murtala Muhammed International Airport.

Six people were injured but all are said to be in stable condition, Nigerian authorities said in a statement. Fourteen people were trapped in the control tower before being evacuated by emergency teams.

The fire appears to have started at about 3pm in a server room on the first floor of Terminal 1.

The flames damaged the airport’s departures hall which is undergoing a $500 million renovation.

Nigeria’s Airspace Management Agency said it was working to establish a temporary control tower to restore operations.

Flights resumed at 7.30 pm.
