The authorities in the central Nigerian city of Jos have arrested dozens of men suspected of being involved in sectarian fighting which has claimed the lives of hundreds of people.
The army was sent in to reinforce a 24-hour curfew in the city, which lies at the crossroads of the country’s Muslim north and Christian south.
Dozens of weapons have been seized, including knives, machetes and firearms. Police and soldiers are said to be patrolling the streets with orders to shoot troublemakers on sight.
Nigeria’s 140 million people are roughly split equally between Muslims and Christians and the two communities generally co-exist peacefully. Competition for the country’s vast natural resources is usually what triggers fighting.
But this time violence flared following allegations that a local election had been rigged – reviving old rivalries between the Christian and Muslim communities.
The death toll is thought to be around 400 with many more injured – but those on the ground say the real figures may be higher.
