A huge fire has ravaged the main international airport in the Kenyan capital, Nairobi.
Jomo Kenyatta International Airport (JKIA) - a key regional hub - has been closed, passengers evacuated and incoming flights diverted.
The fire is now said to have been contained but there has been criticism of the time it took emergency services to respond.
Images from the scene showed flames leaping from one of the main buildings.
There have been no reports of any casualties and the cause of the fire is not clear.
Jomo Kenyatta International Airport is the regional hub for East Africa, with many long-distance flights landing there to connect to countries across the region.
The airport is the main gateway for European tourists and is also crucial for the country's key flower export industry, so the fire could have a huge economic impact, says the BBC's Emmanuel Igunza at the scene.
Shares in Kenya Airways fell in early trading on Wednesday.
'Water shortage'
The cabinet secretary for transport, Michael Kamau, said the fire was "very severe" and urged people to stay away from the area.
Dark smoke could be seen billowing into the sky across much of Nairobi as the fire - which began at approximately 04:30 local time (01:30 GMT) - took hold.
The first fire engines arrived as late as 07:00, our correspondent says - by which time the blaze was ravaging the arrivals hall.
Some witnesses also said traffic jams had prevented emergency vehicles getting through.
Shocked would-be passengers stood outside the airport, bags in hand, watching the blaze.
Nairobi resident Barry Fisher - who had hoped to travel to Ethiopia on Wednesday - described the scene as chaotic.
"There was no one stopping any traffic going to the road to the airport," he told AP news agency.
"A number of fire trucks and ambulances were trying to negotiate their way through the lane... They were trying to weave their way through a solid two lanes of cars."
American student Emily Mosites was in the airport trying to get a flight to Kisumu when the fire broke out.
"There was no emergency direction on leaving - I just stood there watching the fire. There were no officials to tell anyone what to do.
"I wasn't told whether or not there were any flights departing. So I thought this was insane and decided to leave."
The government also admitted that firefighters had run "dangerously low on water" and water tankers had had to be sent to bolster supplies.
