At least 30 killed in Nigeria suicide bombings
At least 30 people have been killed in a suicide attack in north-eastern Nigeria, officials say.
Another 40 have been injured, according to the State Emergency Management Agency.
The bombers detonated their explosives outside a hall in Konduga, Borno State, where football fans were watching a match on television.
Jihadist group Boko Haram is being blamed for the attack, though it has not claimed responsibility for it.
It has frequently carried out bomb attacks in the state.
Ali Hassan, the leader of a self-defence group in Konduga, told the AFP news agency that the owner of the hall argued with one of the bombers as he tried to enter the venue.
“There was a heated argument between the operator and the bomber who blew himself up,” he said.
Boko Haram has claimed 27,000 lives and forced some two million people to flee their homes.
