Frustrated viewers voiced their anger on internet message boards after they missed Germany's second goal in their 3-2 victory over Turkey following an electrical storm.

The television screen went red for more than five minutes and only the commentary could be heard.

Gary Lineker, the BBC's host, later apologised for the loss of transmission.

Broadcasters around the world, including ESPN, were affected by the hitch, which occurred around an hour into the game.

Although the match was being played in Basle, Switzerland, the storm struck Vienna in Austria where the television feed was based.

It is the second time in two months that technical problems have beset coverage of a major football match.

In May Rangers fans rioted in Manchester when a city-centre screen broke down before their team's Uefa Cup final against Zenit St Petersburg.

Fans bombarded internet chatrooms with complaints.

One said: "I pay for my TV licence and I'm outraged. What a load of c**p from the BBC."

Paul Foster joked: "Don't be telling Rangers fan about this powercut."

Justin Freeman, 38, said: "I know the BBC could not help there being a storm but it was so annoying that a crucial goal was scored when the pictures went off."

A BBC spokesman stressed that it was not their fault.

"This was due to the loss of the host feed provided by the host broadcaster, UEFA," she said.

"At this stage we cannot be sure what caused the interruption but we believe it was a power failure due to the extreme weather conditions currently being experienced in Austria. All countries across the world receiving the feed lost pictures and sound."

She said that the switchboard had not fielded any complaints because the BBC was not responsible for the pictures.

"We had people ringing up to ask what had happened, but it was more reaction than complaints," said the spokesman.

Officials shut down Vienna's main Euro 2008 fan zone and evacuated fans after the thunderstorm lashed the Austrian capital with heavy rain, high winds and lightning.

Authorities said they gave the order to close the fan zone after the storm unleashed winds exceeding 100 kilometers per hour (60 miles per hour).
