Pakistani media reports say one of the two suicide bombers who targeted President Pervez Musharraf last week belongs to an outlawed Pakistani Islamic group.
An intelligence official has been quoted as saying 23-year-old Mohammed Jameel was a resident of Rawalakot in the Pakistani Kashmir and belonged to the outlawed Jaish-e-Mohammed.
General Musharraf banned the group along with several others in an attempt to curb Islamic militancy in Pakistan.
On Sunday, Pakistani authorities said the attackers belonged to a terrorist network which has been active from Afghanistan to Kashmir.
Last week, General Musharraf narrowly survived twin bombings in the garrison city of Rawalpindi, which killed 15 people and wounded 45 others.
India has also blamed the group for attacking its parliament in New Delhi in December 2001, an incident that brought it to the brink of war with Pakistan.
Pakistani media say the other suicide bomber has been identified as an Afghan from the ranks of Muslim militant groups active in Pakistan's North West Frontier Province.
