You are wrong it may not a part of the umbrella group but it has close links with AQ,TTP and Afghan Taliban factions.
Jundallah ("Soldiers of Allah") is based in Karachi and maintains close ties with both al Qaeda and the Taliban. The group is best known for trying to assassinate General Ahsan Saleem Hyat, commander of the Pakistani Army's Karachi Corps, in June 2004. Shortly after the assassination attempt, Pakistani security officials arrested Jundallah's emir, Ata-ur-Rehman, and his deputy, Shahzad Bajwa.
Rehman, who holds an MSc degree from Karachi University was trained in Afghanistan and later, he established the militant organisation in 2003. At present, Rehman is imprisoned in Karachi Central Jail after the Anti-Violent Crime Unit arrested him in 2003 from his house in Model Colony.
Jundallah also has a history of targeting Shia. The group's two most high-profile attacks against Shia took place in May 2004, when Jundallah killed 38 Shia worshipers in separate attacks at the Hyderi Mosque and the Jinnah Road Mosque in Karachi.They targeted Shiite Bus passengers too several times.
Jundallah has also established a presence in the Taliban-controlled tribal agency of South Waziristan. The terror group is known to have set up a camp in the Shakai area, which is administered by Haji Omar Khan, a senior Taliban leader in South Waziristan who has strong ties to Mullah Omar.
In March 2008, the US killed a dual-hatted Jundallah and al Qaeda operative known as Dr. Arshad Waheed in a drone airstrike in South Waziristan. Both Waheed, who had close links to Ata-ur-Rehman, and Waheed's brother Akmal, who is also a doctor, had been detained by Pakistani army in 2004 for treating Jundallah fighters involved in the assassination attempt on General Hyat. It is unclear why Pakistani security forces freed the brothers. Waheed returned to South Waziristan to serve as a military trainer for al Qaeda's Shadow Army. After Waheed's death, Mustafa Abu Yazid, who was al Qaeda's overall leader in the region before he himself was killed, gave a eulogy for him.
And in June 2010, the US killed Hawza al Jawfi, an Egyptian who is said to have led Jundallah, during a drone strike in the village of Karikot near Wana, the main town in South Waziristan. Jawfi was sheltering in a safe house that was known to have been used by al Qaeda operatives. At the time, the Wana area was administered by Mullah Nazir, a senior Taliban leader who openly professed his allegiance to al Qaeda, and was killed this January in a US drone strike in the Birmal area of South Waziristan.
