The Haqqani Network
ORIGINS: Founded by Jalaluddin Haqqani, an Afghan guerilla. In the 1980's, Jalaluddin received American support in fighting against Soviet troops in Afghanistan.
WHY TARGETED: The United States believes the al Qaida and Taliban-linked Haqqani network is responsible for a series of high-profile attacks against U.S. and NATO forces in Afghanistan, including a 2011 attack on the U.S. embassy in Kabul that left four people dead and more than 100 wounded.
PREVIOUS US EFFORTS: The United States has previously imposed sanctions on Haqqani leaders, including founder Jalaluddin Haqqani and two of his sons. In late August, U.S. and Pakistani officials confirmed that Badruddin Haqqani, the commander of the group's day-to-day operations, was killed in a drone strike.
PAKISTAN: Pakistan has denied assertions that the Haqqani network has close ties to elements of Pakistani intelligence.
