Kenyan officials say a building collapse in the capital, Nairobi, has killed at least two people and trapped scores of others.

Authorities say the six-story building was under construction when it crashed to the ground Tuesday.

Rescue teams were searching desperately through the rubble for survivors.

The Kenyan Red Cross says a number of people were injured in the collapse, though it is not clear how many.

The structure is located near the Jomo Kenyatta International Airport in eastern Nairobi. There was no immediate word on the cause of the collapse.
