Shops and homes were set ablaze and razed in the attack Monday night on Gamboru Ngala, on Nigeria's border with Cameroon, Borno state information commissioner Mohammed Bulama told The Associated Press by telephone.
As many as 300 people were killed in the attack, according to local newspapers. The militants sprayed gunfire into the crowds of people at a busy market, that is open at night when temperatures cool in the semi-desert region, reported ThisDay newspaper.
Nigerian federal Senator Ahmed Zannah said the attack lasted about 12 hours, according to the newspaper. The insurgents set homes ablaze and gunned down residents who tried to escape from the flames, reported the paper.
Boko Haram's five-year-old Islamic uprising has claimed the lives of thousands of Muslims and Christians. More than 1,500 people have died in their attacks so far this year. The insurgents say Western influences are corrupting and they want to impose an Islamic state in Nigeria, a country of 170 million of whom half are Christian.
