Nigeria’s northern neighbour, Niger Republic has said it will not be involved in any attempt to retake the north-east Nigerian town of Baga from Boko Haram.
Bodies reportedly lay strewn on the streets of the town following an assault by the Islamists on Wednesday, with hundreds feared killed.
The town is near the border with Chad and had housed a military base staffed partly by multinational forces.
Soldiers from Niger had been there but were not present when it was attacked.
The BBC’s Nasidi Yahaya in Abuja says the decision of Niger is clearly a big blow to Nigeria which boasts that the presence of a multinational task force in the area would help defeat Boko Haram militants.
The removal of the troops from Niger means Nigeria’s neighbour now has no forces directly involved in tackling Boko Haram.
Chad has also withdrawn its forces.
