Kenyan police say a cabinet minister who once served as Kenya’s vice president has been killed in a helicopter crash near the capital.

The officials said Internal Security Minister George Saitoti was one of seven people killed in the crash on the outskirts of Nairobi.

Saitoti, an American-trained economist and mathematician, was one of the most visible figures in Kenyan politics.

He announced last year that he would seek the Kenyan presidency in 2013.
