At least 13 people have been killed in a bomb blast at a venue televising a World Cup match in northern Nigeria, medics say.

Witnesses in Damaturu, in Yobe state, say a suicide bomber in a tricycle taxi detonated explosives as people watched Brazil’s match against Mexico.

At least 20 people are said to be seriously injured.

Public screenings of the World Cup in one other Nigerian state have been cancelled due to threats by Boko Haram.

Three areas, including Yobe, are under a state of emergency amid attacks suspected to have been carried out by the Islamist militants.
