He is head of the Haqqani network and believed to be the main bridge between Al Qaeda, Afghan Taliban, and militant outfits in North Waziristan. Known among jihadis as “Khalifa” and the “soul of Jihad,” Mr. Haqqani has ties to Al Qaeda's Osama bin Laden and Ayman al Zawahiri.
He is the son of commander Jalaluddin Haqqani, a former Taliban minister for tribal affairs. Siraj’s four brothers – Nasiruddin, Badruddin, Khalil, and Ibrahim – are the group's military shura (council). Nasiruddin is believed to have conducted fundraising in Saudi Arab and other Gulf states between 2006 and 2009. Badruddin handles politics, settling disputes between militant outfits. Siraj's youngest brother, Mohammed, was killed in February this year by a US drone strike.
