NAIROBI - Thirty four people died in central Kenya when their bus veered off a bridge and plunged into a river valley, local media reported on Monday.

Reuters quoted the Daily Nation and Standard newspapers as saying that the incident occurred on Sunday evening in Tharaka Nithi County, when the bus belonging to the Modern Coast company travelling from Meru to the port city of Mombasa veered off the Nithi Bridge, and fell into the valley 40 metres below.

"Up to now, we have lost 14 women, 18 men and two girls, so the total deaths are 34. We have rescued 11 who are undergoing treatment in hospital," Tharaka Nithi County Commissioner Nobert Komora told NTV Kenya television near the crash site.

Nation reported Komora as saying that initial investigations showed the bus's brakes may have failed, preventing its driver from properly turning on a sharp bend at the bridge.
