Security forces have reported that Boko Haram militia attacked two villages in Diffa, the south of Niger, killing at least 30 civilians overnight.
The attack is identified as this week’s second biggest cross-border attack by the armed group, following the suicide bombings in N'Djamena, Chad, that killed 34 people on Monday.
Boko Haram militants reportedly drove into villages in Gueskerou, on the border between Niger and Nigeria, with cars and motorbikes and randomly fired at residents before setting their homes which sheltered others, on fire.
"In all, at least 30 were killed. Some of them died when the houses were set alight," said one security official. He added that the death toll could increase as some of the injured had very serious burns.
Southern Niger has been frequently attacked this year by Boko Haram, forcing the government to declare a state of emergency and arresting more than 600 people that is allegedly linked to the militant group.
Nigeria’s newest President, Muhammadu Buhari often meets regional counterparts to establish a plan to overcome Boko Haram’s deadly insurgency that has created much turmoil in the region and killed over a million since its offensive began.
Last week, he asked his neighbours to support his country in a bid to control the force throughout his campaign against Boko Haram.
The Nigerian army recently carried out an offensive backed by Niger and Chad, to recapture parts of northeastern Nigeria which were captured by Boko Haram.
Boko Haram had previously announced its pledge of allegiance to ISIS.
