A bus missed a curve on a road in southwestern Bolivia Wednesday, causing an accident that killed 25 people and injured 30 others, police told a local radio station.

Major Rufo Munoz, the chief of the traffic police in Potosi, said the bus was carrying 55 passengers from Potosi to La Paz, 574 kilometers (350 miles) to the north.

"According to the technical report, it is presumed that the driver was inebriated and because of a lack of visibility did not see a curve, causing this traffic accident," he told Erbol radio.

He added that the victims included men and women of different ages.

The injured were being taken to a hospital in Potosi, but some were still at the scene awaiting transfer, he said.
