(CNN) -- A truck on its way to Lagos, Nigeria, crashed into several vehicles and caught fire, killing an unconfirmed number of people, police said on Sunday.
Frank Mba, a police spokesman, said the truck's brakes failed outside Lagos, Nigeria's commercial capital. The driver lost control and collided with other vehicles, sparking a fire, he said.
Rescue workers took some people to a hospital, while other people were killed in the crash, Mba said. He did not know how many people had died.
