Washington DC: American experts suspect the role of Pakistani intelligence agency ISI in "supporting the masterminds" of the Pulwama terrorist attack in which at least 37 CRPF personnel were killed.

Pakistan-based Jaish-e-Mohammad (JeM) has claimed responsibility for one of the deadliest terror attacks in Jammu and Kashmir. The experts on South Asia said the terror strike shows the United States has failed to persuade Pakistan to act against Jaish-e-Mohammad and other terrorist groups. "The self-proclaimed involvement of JeM in the attack raises serious questions about the role of the ISI in supporting the masterminds of this operation," said Bruce Riedel, a former CIA analyst.
