Christian groups are out on the streets of Jos city in central Nigeria to protest against mass killings by suspected herdsmen in several villages in the state.

The police say 86 were killed on Saturday but local leaders say the number is more than 200.

The killings are said to be in retaliation to an attack on herdsmen. At least five people were killed and cattle were stolen in the attack.

The protesters say the authorities are not doing enough to stop the violence.

On Tuesday President Muhammadu Buhari met community leaders in Jos - the capital of Plateau state - and reiterated his commitment to tackling communal violence in the state and other parts of the country.
