Some women were abducted along Pulka road in Gwoza local government area of Borno state on Tuesday evening.
The victims were on their way to a neighbouring local government when the insurgents attacked the bus they were in.
Muhammed Buba, one of the passengers on a vehicle that was attacked, told TheCable that many people sustained injuries in the attempt to escape.
Buba did not say if anyone was killed but added that there were sporadic gunshots from different directions during the attack.
Idrissa Hamisu, another victim, said the insurgents came in two Toyota Hilux buses.
“Many who were caught in the attack were women who lacked the strength to run away. The incident occurred around on Tuesday,” he said.
Hamisu said the insurgents also engaged in serious gun battle with troops in the area.
“I don’t know if the soldiers were able to save the passengers but many women were abducted in the attack,”he said.
Texas Chukwu, spokesman of the army, was not available for comments as his telephone line was out of reach when TheCable attempted to speak with him on Wednesday.
The attack comes 48 hours after many soldiers were reportedly killed in the north-east but the military denied the killings, describing the report as fake news.
