Four Brazilian college students were killed and 36 were injured when a bus crashed on a dangerous stretch of mountain road in southern Peru, police said on Tuesday, according to Reuters. The bus was carrying the students to the World Social Forum in Venezuela when the driver lost control of the vehicle on a wet, mountainous road near the southern Andean city of Arequipa just before midnight, police said. Hundreds of people die in bus crashes every year in Peru because of perilous roads, poorly maintained vehicles and bad judgment by drivers in treacherous weather conditions. At least 24 people have died in bus crashes so far in January, according to local transit police data.
