At least 20 people have been killed and 30 others injured in Bolivia after a bus’s brakes failed and it plunged down a ravine. The accident happened on a road known as the “Highway of Death” due to the high number of accidents there. Those injured in the crash say the driver and his assistants jumped from the bus once they realized it wouldn\'t stop. Bolivia\'s government has brought in tougher driving laws in recent years to reduce the number of accidents.
