A spokesman for Kenya’s prime minister says a cabinet minister and assistant minister were killed when their small plane crashed.

Salim Lone, spokesman for Prime Minister Raila Odinga, called it “unbearable news.”

The plane carrying Roads Minister Kipkalya Kones and Assistant Home Affairs Minister Lorna Laboso went down Tuesday in southwestern Kenya.

An official at Kenya’S Civil Aviation Authority confirmed that the lawmakers were on the six-seater plane.
