English paper Guardian said on Wednesday that it saw 'secret documents' which prove that the mysterious jamming was caused by Jordan.

"Al Jazeera confirms that the source of the disturbance on its sports channel during the World Cup came from Jordan," the channel said.

"The channel is disappointed to find out that the jamming was caused by an Arab country.

"The channel will officially ask the Jordanian government for an explanation."

Guardian suggested that Jordan 'retaliated angrily after the collapse of a deal that would have allowed football fans there free access to the matches'.

Jordan insisted that Al-Jazeera's accusations are 'false and baseless'.

"The Jordanian government categorically denies allegations made by unnamed sources to the Guardian newspaper that it was behind the jamming of Al Jazeera's broadcast of the World Cup," a senior government official said in a statement.

"These allegations are absolutely baseless and unacceptable and any examination will prove these allegations false."

Al-Jazeera hinted that Egypt were the source of the interference during the World Cup finals in South Africa.

Egypt, who own the Nilesat satellite, denied any involvement in the jamming.
