More than 300 Boko Haram fighters have been killed in military operations in north-east Nigeria, the army says in a BBC report.
According to the same report, a number of militants had also been captured and weapons and equipment seized, defence spokesman Chris Olukolade said.
Two soldiers had lost their lives and 10 others were wounded during the operation over the last two days in Borno state, he added.
The deaths have not been independently verified.
Nigerian forces have been accused of overstating enemy casualties in the past.
Boko Haram attacks on civilians and the military have killed thousands since the group launched its violent campaign for a breakaway Islamic state in 2009.
Nigeria, Chad, Cameroon and Niger have recently formed a military coalition and have claimed gains against the group.
