Explosion outside Nightclub in Nigerian Capital

An explosion went off outside a nightclub in the Nigerian capital Abuja, breaking windows and damaging cars, but no casualties were reported, the country's emergency agency said on Saturday.

"No human casualty," Yushau Shuaib, spokesman for the National Emergency Management Agency, said of the blast late Friday. "The explosives were suspected to have been planted on a tree opposite Kryxtal Lounge."

An AFP reporter who visited the scene saw a damaged tree and broken windows at the nightclub, a barber shop and a nearby bank.

Nigeria has been hit by scores of bombings blamed on Islamist group Boko Haram, including some in and around Abuja.

A suicide bomb attack on U.N. headquarters in Abuja in August killed at least 25 people, while another at the Abuja office of one of the country's most prominent newspapers left at least four dead.

On Friday, President Goodluck Jonathan fired his national security adviser and defense minister as fears mounted over spiraling unrest in the country's north, where Boko Haram's insurgency has been based.
