Nigeria suicide blast kills two
Two people have died in a suicide bombing in the car park of police headquarters in Nigeria's capital Abuja.
Police say the suicide bomber and a traffic warden who was in the car to show the driver where to park were both killed in the attack.
Nigeria has experienced a rise in bomb attacks in public places over the last year, but suicide bombings are rare.
Police blame a radical Muslim sect locally known as Boko Haram.
"They have been issuing threat upon threat," a spokesman said.
Seven injured people were taken to a hospital and two have since been discharged.
