All schools and universities in Chad have been closed after deadly protests over new regulations requiring motorbike riders to wear a helmet.

At least three people were killed over several days of student-led protests.

Motorbikes are a popular form of transport in Chad, and are frequently used as taxis.

Many people oppose the new safety regulation, arguing that helmets are too expensive, as well as too hot for the climate.

Helmet prices have tripled since the new regulation was introduced earlier this month.
