A bus crash in Kenya Wednesday  killed at least 55 people , including nine children.

Authorities believe about 15 people survived.

The crash happened on a highway around 5 in the morning local time.

The bus was traveling from Nairobi to Kisumu, a port city about 200 miles away.  Authorities said  they believe the driver lost control of the vehicle while going down a steep slope.  Local police said the bus was not licensed to operate at night, according to the Washington Post.  A World Health Organization study a few years ago found that the roads in Kenya are some of the most dangerous in the world.

Kenya's president tweeted his condolences and wished those who were hospitalized a quick recovery.
