FIFA said Sunday it would help Middle Eastern television network al-Jazeera track down the cause of black-outs in its broadcast of the World Cup's opening match in South Africa, according to dpa. "FIFA is supporting al-Jazeera in trying to locate the source of the interference in the transmission of the FIFA World Cup," FIFA spokesman Nicolas Maingot said in Johannesburg. The black-outs are "unacceptable to FIFA", said Maingot, whose organization has sold the broadcasting rights of the tournament to al-Jazeera Sports and to other broadcasters in some 100 countries around the world. The Doha-based broadcaster faced the wrath of viewers over the weekend after leaving them staring at blank screens for long periods during the opening game of 2010 World Cup between South Africa and Mexico. -- SPA
