A cargo air plane crashed into a commercial building shortly after takeoff today from the Kenyan capital's main airport, the busiest in East Africa, aviation authorities said.

"A Fokker 50 cargo plane with four people onboard has this morning crashed at a commercial building," after taking off from Nairobi's Jomo Kenyatta International Airport (JKIA), Kenya Airports authority said in a statement.

It was not immediately clear if there were any casualties, but police sources said all on the plane were feared dead.

The plane crashed shortly after dawn today in an area outside the airport where there are office buildings and factories which would be expected to be largely empty at that hour.
