"The resolution was passed unanimously. All 102 lawmakers present voted favourably," lawmaker Mohamed Ben Omar said yesterday. Another member of parliament said the resolution authorises the country to send some 750 troops to Nigeria.
Niger, while housing thousands of refugees from the conflict, had been mainly spared the violence until last week, with a number of attacks carried out on its territory in recent days in the run up to the vote.
On Saturday, Nigeria and its neighbours -- Chad, Niger, Cameroon and Benin -- agreed to muster 8,700 troops, police and civilians for a wider, African Union-backed force against Boko Haram.
