NAIROBI, Kenya -- A train crashed into a passenger bus as it passed through a rail crossing in the capital, Nairobi, killing at least 11 people, emergency officials said.

Kenya's National Disaster Operation Centre said Wednesday the crash also injured several people. Kenya's Red Cross said at least 11 people were killed in the crash.

Photos showed a white passenger bus half crumpled and tilted on its side. Hundreds of people gathered at the scene.

Road accidents with high death tolls are common in Kenya. Streets and highways often lack basic safety features such as reflectors or street signs. Most railroad crossings do not have gates or flashing lights.

In addition, crowded buses frequently speed and pass other cars to cut down travel times.
