LA PAZ, Bolivia (AP) — A bus missed a curve on a road near Bolivia's capital on Friday and plunged down a ravine, killing at least 15 people and injuring 19 more, officials said.

Local fire department chief Ismael Villca told Erbol radio that the bus was a half hour out of the capital half an hour earlier en route from the northern town of Coripata.

It was the third serious accident of the week in Bolivia. A small bus collided with a cargo truck on Tuesday, killing 14 people west of La Paz, while a bus and truck collided on a road to the Uyuni salt flats in southwestern Bolivia, killing three.
