Sirajuddin "Siraj" Haqqani (alias "Khalifa" born c. 1973) is a Pashtun warlord and military leader who fights against American and coalition forces from his base within North Waziristan in Pakistan, where it is claimed he provides shelter to Al Qaeda operatives. His father is Jalaluddin Haqqani, a famous mujahideen and military leader of pro-Taliban forces in Afghanistan and Pakistan. His forces have been accused by the coalition forces of carrying out the late-December 2008 bombing in Kabul, Afghanistan at an Afghan elementary school near an Afghan barracks that killed several schoolchildren, an Afghan soldier, and an Afghan guard; no coalition or US personnel were affected.
Haqqani has admitted planning the January 14, 2008 attack against the Serena Hotel in Kabul that killed six people, including American citizen Thor David Hesla, as well as having planned the April 2008 assassination attempt on Afghan President Hamid Karzai.
