A commanding officer and seven others were killed when Boko Haram insurgents attacked two Nigerian army bases in Borno State on Sunday.
The terrorists have intensified attacks on army camps in recent weeks.
AFP reports that the Islamic State West Africa Province (ISWAP), an affiliate of the dreaded Boko Haram group, on Sunday, attacked a base in Ajiri, about 20 kilometres from Maiduguri, the state capital.
A similar attack had been carried out earlier on Saturday night, when the insurgents hit a base in Rann in the same state, the report quotes military sources as saying.
In Ajiri, troops fought a two-hour gun battle with the insurgents in gun trucks and on motorbikes who eventually breached the base and forced troops to withdraw.
“The commanding officer of the base… paid the supreme price while six civilians who were caught up in the fight were also killed,” one of the military sources said.
Another source confirmed the toll and said the militants escaped with weapons from the base.
On Saturday, the jihadists attacked a base in Rann, 172 kilometres from Maiduguri, but were beaten back by troops using artillery.
“They came in six gun trucks and met a stiff resistance from troops at the base. Two of the gun trucks were hit by troops artillery fire. The other four fled,” another military source was also quoted to have said.
One civilian who was wounded later died in hospital.
