The numbers are still rising. Afghanistan’s National Directorate of Security (NDS), the country’s intelligence agency, took responsibility for failing to prevent the assault, with one official admitting to Foreign Policy that the NDS had prior intelligence that it would occur. But even as nobody has yet claimed credit for the bombing, the NDS has pinpointed a culprit.
Just hours after the explosion, the NDS pointed to the Haqqani Network, an insurgent group in the Afghan-Pakistani borderlands that shares close ties with the Taliban, as the perpetrators. But Afghan intelligence lay ultimate blame with their Pakistani counterpart, Inter-Services Intelligence (ISI), which it claimed had planned the blast.
