Al Jazeera television said it was investigating reports of reception disruptions across the Middle East on Saturday, a day after it said its signal had been jammed on several frequencies."We are not sure of the cause but we are looking into it," an Al Jazeera spokesman said.
The Qatar-based news channel's signal was sporadically disrupted in countries including Saudi Arabia, the United Arab Emirates and Egypt throughout Saturday.
Al Jazeera's coverage of the political unrest in the Middle East and North Africa has been widely watched.
It reported the jamming on Friday on its website, where it offered alternative frequencies on the Arabsat, Nilesat and Hot Bird satellites.
The station has closely followed events in Libya, Bahrain and Yemen, contacting protesters and government backers by telephone and often airing footage of events sent via the Internet.
Earlier this month, Egypt's Nilesat cut off Al Jazeera's signal for more than a week after authorities there ordered it to stop operations in Egypt during the unrest that ultimately ended president Hosni Mubarak's 30-year rule.
Launched in 1996, Al Jazeera has more than 400 reporters in over 60 countries, according to its website. It says it can reach 220 million households in more than 100 countries.
