The Afghanistan Government has said they suspect involvement of Haqqani network behind the suicide bombing on Wednesday that killed seven Central Intelligence Agency (CIA) personnel in eastern province of Khost. Interior ministry spokesman Zamari Bashari said the government has not yet determined who was responsible for the attack but suspicion centred on Haqqani network adding that it is involved in most of the attacks and violence in Khost. The Haqqani network, headed by Jalaluddin Haqqani, who once fought against the Soviets, is suspected of carrying out a series of suicide bombings and other attacks on US forces in the eastern provinces, which borders Pakistan. Both the factions of Afghan and Pakistan Taliban have claimed responsibility for the attack but such claims are often to gain publicity for their success against foreign forces. The CIA agents killed at the base are believed to have been running intelligence operations to support attempts to bring greater military pressure on Haqqani network, believed to have links to al-Qaeda. The US has called upon Pakistan to broaden its fight against militants to safe havens used by the Haqqani network in North Waziristan, which is across the border from Khost. Pakistan’s security agencies, which have long-standing links with Haqqani network and other Afghan militant groups, have refused to heed the request, arguing they lack the capacity to fight on several fronts.
