Interior Minister Aftab Sherpao says there is no truth to the media reports, which quote Pakistani intelligence officials.
Those officials, speaking on condition of anonymity, said that security forces arrested the seven suspects in late April in eastern Punjab province. The officials said the plot's mastermind was a militant who was freed from prison in Afghanistan several months ago.
The reports come after Pakistani authorities on Wednesday announced the capture of Abu Farraj al-Libbi, whom they describe as the third-in-command of the al-Qaida terrorist network.
Pakistan accuses him of orchestrating two unsuccessful attempts to assassinate President Pervez Musharraf in December 2003.
