Boko Haram repeated its attacks on the border town of Diffa on Saturday night, engaging in clashes with Niger's army before being repelled at around 5 a.m. local time, residents told AP.
On Friday, neighboring Niger's armed forces claimed that 109 Boko Haram fighters were killed after the group attacked the country's border towns. The attack followed Niger's decision on Thursday to commit troops to the struggle against the group.
On Saturday, Niger, Nigeria, Cameroon and Chad pledged to deploy 8,700 troops, police and civilian personnel in the struggle against Boko Haram.
On Saturday night, Nigeria's electoral commission decided to delay the country's general election until March 28, amid criticism from civil society groups and the US State Department.
Boko Haram is a militant group, which aims at establishing an Islamic state in northern Nigeria. Large swathes of land in the Borno State, as well as in neighboring Adamawa and Yobe are believed to be under control of the Islamists. The Boko Haram insurgency has left over 13,000 people dead since 2009.
