At least 19 people are now listed as killed in the second car bomb in a month to hit the Nigerian capital, officials says. It comes days before the city is set to host a major international conference.
The explosion, on a busy street in Abuja on Thursday, occurred near a bus station where 70 people were killed in an April 14 bomb attack, Reuters says. The Islamic extremist terrorist network Boko Haram claimed responsibility for last month's attack.
Police Superintendent Frank Mba told reporters on Friday that the toll had reached 19 dead with as many wounded.
Abuja is hosting the World Economic Forum on Africa May 7-9. The conference is to feature Chinese Premier Li Keqiang. It attracts leaders, policymakers, philanthropists and business leaders from around the world to discuss Africa's economic growth prospects.
The latest violence comes as police in the country said the number of schoolgirls held by Boko Haram militants after a mass kidnapping last month was 276, an increase of more than 30 from earlier reports.
Police Commissioner Tanko Lawan revised the number of girls and young women who have escaped to 53.
The abduction of the girls in Chibok in northeastern Borno state was among the most shocking attacks by Boko Haram in five years of separatist conflict that has left thousands dead in the country's north and central regions.
According to The Associated Press, Lawan says that the figures of the number of girls taken increased "because students from other schools were brought into one school for final exams last month after all schools in Borno state were shut because of attacks by Islamic extremists. Communications are difficult with the military often cutting cell phone service under a state of emergency and travel made dangerous on roads where travelers are frequently attacked by the militants."
NPR's Ofeibea Quist-Arcton, reporting from Dakar, Senegal, says there's still no word on the fate of the girls.
There are a number of theories, including forced marriages and/or being moved across the border to either Chad or Cameroon, Ofeibea says.
Weeks after the April 14 kidnapping, "the people want answers," she says.
"Someone has to know something, even in the government, because remember this happened at night, after curfew — 22 pickup trucks and 30 motorcycles riding down the main road in plain sight," she says.
The parents have a sense of hopelessness and despair. They've held protests in Abuja and the city of Chibok this week.
"Remember, these are young women who were/are to be the cream of the crop, big dream in an area with such little opportunity for education, especially for girls," Ofeibea says. "These are ones destined to go on to university, to be doctors, teachers. These girls lives are ruined."
