Boko Haram insurgents from neighbouring Yobe State have infiltrated at least four local government areas of Bauchi State, destroying some facilities.

The Secretary to the Bauchi State Government (SSG), Alhaji Sabiu Baba, disclosed this at a press conference on Monday.

He identified Zaki, Gamawa, Darazo and Dambam as some of the affected local government areas.

Similarly, militants from the Islamic State-backed faction of Boko Haram, the Islamic State West Africa Province (ISWAP), formerly known as Jamā’at Ahl as-Sunnah lid-Da’wah wa’l-Jihād had attacked a military base in Borno state, killing an army commanding officer.

It was gathered that the bloody encounter also left six other soldiers dead.

The terrorists had on Sunday invaded Ajiri village in the Mafa Local Government Area of the state, attacking a military base and dislodging the troops.

Ajiri is a community in the Mara Local Government Area of Borno State, which is about 52km from Maiduguri, the Borno State capital.

It was gathered that the troops fought a two-hour gun battle with the insurgents in gun trucks and on motorbikes who eventually breached the military base and forced the soldiers to withdraw.

The attack came a few days after the insurgents attacked a Nigerian Army location at 156 Battalion in Mainok area, Borno State, killing over 30 soldiers.

Mainok is the headquarters of the Kaga Local Government Area of Borno state.
