Scores of bodies from that attack - described by Amnesty International as possibly the "deadliest massacre" in the history of Boko Haram - are reported to remain strewn in the bush.
District head Baba Abba Hassan said most victims in the Baga attack were children, women or elderly people who were not able to escape when insurgents forced their way into the town by firing rocket-propelled grenades and assault rifles.
"The human carnage perpetrated by Boko Haram terrorists in Baga was enormous,'' Muhammad Abba Gava, a spokesman for a civilian defence group that fights Boko Haram told the Associated Press .
Boko Haram launched a military campaign in 2009 to create an Islamic state.
It has taken control of many towns and villages in north-eastern Nigeria in the last year.
The conflict has displaced at least 1.5 million people, while more than 2,000 were killed last year.
