A suicide bombing in the parking lot of police headquarters in Nigeria's capital Thursday has killed two people, police said. Olusola Amore, national police spokesman, told journalists that two people were confirmed dead after a car blew up in the parking lot outside the building of the police headquarters Thursday morning. Police say the suicide bomber and a traffic warden who rode in the car to show the driver where to park were both killed in the attack. Amore read an official statement that said that "the body of the suicide bomber has been recovered and full investigation has commenced." Nigeria has experienced a rise in bomb attacks in public spaces over the last year, but suicide bombings are practically unheard of in Africa's most populous nation.
