LIMA, July 25 (Xinhua) -- At least five people were killed Saturday in a crash involving two passenger vehicles and a light cargo truck in Peru's southern Tacna region, local media reported.

The accident occurred at around 5:30 a.m. local time on a highway near Campo de la Alianza, when an interprovincial bus collided with an interurban passenger vehicle and the truck, private radio station Exitosa reported.
