Thirty soldiers from Niger and two Nigerian troops were killed in a Boko Haram attack on Niger's border with Nigeria, Niger's defence ministry said.
"On Friday, hundreds of assailants of Boko Haram attacked" the position of the army of Bosso, the ministry said in a statement yesterday.
"The counter-offensive conducted early this morning (yesterday) helped to retake control of all the positions in the city of Bosso. The situation is under control", it added.
Since February 2015, Niger has been plagued by Boko Haram attacks in its southeast region.
The armed group frequently stages cross-border raids from their stronghold in neighbouring Nigeria.
