Borno State Police Commissioner Lawan Tanko said that the attackers arrived in the village of Kawuri, riding on pick-up trucks and motorcycles, opened fire at the market, and burned homes. A witness believes explosives may also have been used in the attack. A police bomb squad was being used to search for unexploded ordinances.
Tanko told The New York Times "It is amongst the worst attacks we've had... What is the motive, and how did they enter the village? We are still taking stock of the actual number of people killed."
A state of emergency was declared in May 2013 for Nigeria's northeastern states due to violence.
