At least 17 police officers undergoing specialised operational training have been killed after suspected Islamist insurgents attacked the Nigerian Army Special Forces School in Buni Yadi, Gujba Local Government Area of Yobe State.

The police confirmed the deaths on Saturday, saying the officers were participating in advanced tactical and counter-terrorism training when gunmen launched a coordinated overnight assault on the military facility from multiple directions.

Police spokesperson Anthony Placid, a deputy commissioner of police, said the attack occurred in the early hours of 8 May at about 1:15 a.m.

“The officers paid the supreme price in service to the nation following a terrorist attack on the Nigerian Army Special Forces School, Buni Yadi,” Mr Placid said in a statement.

He added that several Nigerian Army personnel were also killed while repelling the assault, though authorities did not immediately disclose the number of military casualties.
