Nairobi: Kenya's roads minister and an assistant minister for home affairs were feared dead on Tuesday in the crash of a light plane near the Masai Mara game reserve, a spokesman for their party said.

"I am confirming that they were on the plane that crashed. I am not confirming that they are dead, but the police are confirming that all aboard died," Orange Democratic Movement spokesman Salim Lone said.

Narok District police boss Patrick Wambani said all four people in the plane died.

"The plane came down on an unoccupied house and disintegrated, killing all four occupants," Wambani told Reuters in Narok, 120 km west of the capital Nairobi.

In Nairobi, police spokesman Eric Kiraithe said the names of Kones and Laboso were on the flight manifest.
