As many as 30 Manchester United fans are feared dead in Nigeria after they were electrocuted while watching the club's Europa League match against Anderlecht.

Nigerian Police said the fans died after a cable fell on them at a viewing centre in the city of Calabar, capital of the Cross River state.

According to reports, a high tension electric cable that was very close to the viewing centre fell on the building.

The number of deaths and injuries are yet to be confirmed, but the News Agency of Nigeria say there has been at least 30 killed, with many more injured.

Manchester United and the British High Commission in Nigeria have both paid tribute to those who died in the accident.

The British High Commission in Nigeria added: "Our deepest sympathy for the loss of lives in Calabar during a Europa League football match."
