A bomb attack in the north-eastern Nigerian town of Maiduguri has killed at least 25 people and wounded dozens, security sources say. They say they believe the attack, which occurred in a beer garden, was carried out by the Islamist sect Boko Haram. According to the BBC, 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.
