NAIROBI, Kenya — Riot police fired live ammunition and tear gas to disperse Kenyan university students protesting over road safety.

Multimedia University students Tuesday protested the death of one of their colleagues in an accident over the weekend when a minibus taxi overturned. The taxis, called matatus, are Nairobi’s main source of public transportation. About 100 students accused the matatu drivers of reckless driving which they allege is not stopped by police.

Nairobi police chief Japheth Koome said two students, two police officers and two guards sustained injuries in the melee.

The number of people killed in the first three months of this year increased from 2,699 in 2015 to 3,932 in 2016, according to the National Transport and Safety Authority.
