It is reported that a preliminary investigation into the suicide bombing that killed nine at a CIA base in Afghanistan (see December 30, 2009) suggests that the ISI, Pakistan’s intelligence agency, may have played a role. The Jordanian triple agent who blew himself up in the bombing used an unusually compact and powerful type of bomb. According to senior Afghan sources, a preliminary US investigation shows that a chemical fingerprint of the bomb matches a type of explosive used by the ISI. One senior government source says, “It is not possible that the [bomber] received that type of explosive without the help of ISI.” US and Pakistani officials have refused to publicly comment on any suggestions of ISI involvement.
