Not less than 30 Boko Haram members have been reported killed in a clash with troops in a village near Lake Chad and the Nigerian border.
The incident, which was said to have occurred on Monday also resulted in the death of five soldiers from the republic of Niger.
The fighting reportedly started after the army fell into an ambush, leaving six soldiers injured, with two of the militants captured.
Residents say the insurgents were trying to prevent people from praying during the Islamic festival of Eid-el-Kabir.
A military operation by the Multi-National Task Force involving Nigeria, Chad, the Republic of Niger and Cameroon has been fighting the militants in the Lake Chad area where they plan to establish a base.
