A suicide bomber detonated his tricycle at an outdoor World Cup party in Nigeria.
At least 14 people were murdered.
A suicide bomber detonated a tricycle taxi packed with explosives at an outdoor World Cup viewing center in a northeast Nigerian city Tuesday night, and witnesses said several people were killed.
Hospital workers said the death likely will rise with 15 people critically wounded and casualties still coming in to the main hospital at Damaturu, capital of Yobe state.
Police Assistant Superintendent Nathan Cheghan confirmed the explosion but said rescue workers were being careful for fear of secondary explosions. Islamic extremists of the Boko Haram group frequently time secondary explosions to kill people who rush to the scene of a bomb blast.
Cheghan said he had no casualty figures.
There was no immediate claim for the blast. Witnesses were blaming on Boko Haram fighters, who have targeted football viewing centers and sports bars in the past. Two explosions in recent weeks killed at least 40 people in two northern cities.
This follows a bloody attack on Monday when a gunman shot 22 people dead in a village in northeast Nigeria.
