Problem: Article: The tragedy, which claimed the lives of at least seven people, happened when an electric cable fell on fans watching a Manchester United match on TV.
The English club tweeted that its players will wear black armbands on Sunday in memory of the victims.
English football has a large and passionate following in Nigeria.
The high-tension cable fell on a crowded shack which was showing the Europa League quarter-final against Anderlecht.
One witnesses said the building had a zinc roof which conducted the electricity to those watching inside.
In addition to the dead, at least 30 people were rushed to hospital by local ambulances.
Some eyewitnesses said the number of people who died was higher than the official toll of seven.
It is unclear what caused the electric cable to collapse. The BBC understands an investigation into the incident is underway.

Problem: Article: Vote Leave, one of two exit campaigns, has previously accused the CBI of being "the voice of Brussels".
It has written to Carolyn Fairbairn about its concerns.
The CBI said she would give the letter "appropriate consideration" after she joins later this month.
The letter to Ms Fairbairn, who will replace John Cridland as director general at Britain's biggest business lobby group, is the latest move in a row between the two organisations.
Vote Leave has accused the CBI of not being critical enough of policy from the EU.
It said its analysis of CBI press releases suggested that only 1% were critical of the EU.
"The CBI is not properly representing British business interests," said Vote Leave co-treasurer Peter Cruddas, who is also a Tory donor.
The CBI responded by saying: "This petty claim is simply the latest in a systematic attack from Vote Leave/Business for Britain - a single issue campaign group that wants the UK to quit the EU - and whose aim is to neutralise the CBI in the EU debate for representing the views of the majority of our members, who want the UK to remain in a reformed EU."
Vote Leave is one of two campaigns pushing for Britain to exit the EU, the other being Leave.EU.
Three Eurosceptic groups are backing Vote Leave: Conservatives for Britain, Labour Leave and Business for Britain, which wants big changes to the UK's relations with the EU and says the UK should be prepared to vote to leave if reform is not achieved by David Cameron.
Earlier this month, Vote Leave complained to the British Polling Council about a 2013 survey that the CBI conducted with pollsters YouGov and which suggested most members would want to stay in the EU.
The CBI said the poll had been a member survey, not a poll of all British businesses. Vote Leave said this represented a climbdown from the CBI.
Speaking on Monday ahead of the start of the CBI conference, Mr Cridland told the BBC most of its 190,000 members "believe Britain should be in a reformed European Union".
"We are confident the prime minister can bring home the bacon and then we will ask our members again," he said.
Businesses wanted to continue to access the EU's open markets, but without the "wrong sort of regulation", Mr Cridland said. "It's about creating more investment and jobs in Britain."
The CBI will warn at the conference that a "gloomier" global outlook will eat into economic growth in the UK next year.
It has unveiled a "modest" downgrade in its forecast for 2015, saying it expects the economy to grow by 2.4%, down from an earlier prediction of 2.6%, and by 2.6% in 2016, down from 2.8%.
The group also disclosed its first forecast for 2017, saying it expected 2.4% growth, with a gradual rise in inflation hitting household spending.
President Paul Drechsler will call on business leaders to "let their employees, communities, customers and suppliers know what the [EU in-out] referendum means for growth and jobs", in a speech to delegates.
"Whilst there's no uniform view on the subject - neither within the CBI, nor among the wider business community, the majority of CBI members want to remain in a reformed EU," he will say.
"The majority of our members think that - on balance - the advantages of EU membership outweigh the disadvantages."
He will also hit back at another claim from Vote Leave that the CBI is funded by the EU.
"Our critics are saying we're EU fundedâ€¦ 0.6% of our income does come from the European Commission, which chooses to use our top-quality economic surveys as part of its work to collect robust economic data from across Europe," he will say.

Problem: Article: The churchyard of St Leonards Church in Eynsham has enough space for fewer than ten graves.
Attempts to use land near the 13th Century church have not proved viable due to land prices and archaeological concerns.
Reverend Moray Andrews said it was "causing understandable concern in the community".
The church stopped taking reservations for plots ten years ago when the shortage of space was becoming apparent.
Mr Andrews said attempts by the church and parish council since then to find additional suitable land close to the church had been hampered by the cost of archaeological investigations as a medieval abbey is known to have been located nearby.
He said the issue of "over-burying" in the older parts of the graveyard could be explored but moving gravestones would be time-consuming and there was a reluctance in the community to see old graves moved.
Funeral director Annie Green said it was a "major concern" that contingency plans had not been made.
"There is an elderly population in the village. A lot of them are from old Eynsham families and they would expect to be buried in their parish churchyard," she said.
She said most would "not be happy at all" at the prospect of burials at Whitney town cemetery where fees for "out of parish" burials would be higher.
Gordon Beach, chairman of the parish council said: "We've been working with the church for a number of years looking for alternatives - it's not easy, land is at a premium."
