They say they believe the attack, which occurred in a beer garden, was carried out by the Islamist sect Boko Haram.
The group wants to establish an Islamic government in Nigeria.
It has carried out a number of bombings in north-eastern Nigeria, as well as an attack on police headquarters in the capital Abuja earlier this month.
Gunmen on two motorcycles attacked a packed beer garden late on Sunday, officials said.
"The attackers believed to be Boko Haram members threw bombs and fired indiscriminate gun shots on a packed tavern at Dala Kabompi neighbourhood, killing at least 25 people and seriously injuring around 30 others," an unnamed police officer told the AFP news agency. » | Monday, June 27, 2011
