Tragedy struck Nigeria on Tuesday when at least 14 football fans were killed in a suicide-bomb attack while watching a World Cup game in Damaturu, capital of Yobe state.
The explosion occurred during the match between hosts Brazil and Mexico, which ended in a 0-0 draw.
According to Channels TV, the explosives were transported on a tricycle before being set off at the outdoor viewing centre.
The explosion also left around 26 fans injured, with as many as 15 others in critical condition.
Survivors are presently receiving treatment at the Sani Abacha Specialists Hospital in Damaturu with the incident being investigated by the Nigeria Police Force.
Prior to the start of the tournament, some states in the country had banned football viewing centres from showing any World Cup games in order to avoid attacks from the Boko Haram insurgents in the country's north-east.
No group has yet claimed responsibility for the bombing.
