A rush-hour bomb blast Monday at a bus station near Nigeria's capital and other explosions that followed are thought to have killed more than 70 people and injured more than 120.
An Islamist group that believes Western education is sinful and takes other extremist stands is being blamed.
"Fingers are being pointed at Boko Haram, the terrorist network that has been threatening to attack Nigeria's capital," NPR's Ofeibea Quist-Arcton tells our Newscast Desk.
She adds: "Three years ago, Boko Haram claimed responsibility for a deadly suicide bombing at U.N. headquarters in Abuja, killing 21 people. Abuja is hundreds of miles away from the northeast, the main target area of the insurgents, where nearly 1,500 people have been killed this year."
We have posted about Boko Haram many times in the past two years. Among previous attacks blamed on that group:
-- February 2014. More Than Two Dozen Boys Killed In Attack On Nigerian School.
-- September 2013. Militants Kill Students In Dorms At Nigerian College.
-- June 2012. Church Bombings And Reprisal Killings In Nigeria.
On Monday morning, according to the BBC, commuters were "about to board buses and taxis to go to work in central Abuja" when a bomb went off. It's not clear at this point if that was followed by at least one other bomb, or whether subsequent blasts were because fuel tanks in nearby vehicles exploded.
As of 8 a.m. ET, Reuters was reporting that "the confirmed toll ... is 71 killed and 124 wounded so far, [said] police spokesman Frank Mba."
