KARACHI, July 16: Police are still groping in the dark in their investigation into the assassination of the Islami Tehrik leader, Allama Hasan Turabi who, along with his young nephew, died in a suicide bomb attack on Friday.

It was the third suicide bombing this year which has left the police without any substantial evidence leading to any clue to those involved.

In March, a US diplomat was killed when his car was hit by an explosive-laden vehicle driven by a suicide bomber. The police have failed to make any breakthrough in the ensuing investigation over more than three months now.

It was followed by the April 11 blast at Nishtar Park where a suicide bomber killed more than 50 people, including a large number of religious figures, offering prayers during the Eid Miladun Nabi congregation.

Many high-level inquiry committees were formed after each of the blasts and asked to submit their reports within the shortest possible time. However, the reports of none of these committees have been made public.

In the Allama Turabi assassination case, investigators suspect involvement of a militant outfit or the banned splinter group of a sectarian organisation. Sources said that without having found any concrete clue to those involved in the bombing, the investigators were assuming the involvement of some Jihadi outfit or sectarian group.

Sources in the investigation teams said that the severed head found at the scene of the blast in Abbas Town was photographed by Nadra officials with their sophisticated equipment. However, the Nadra authorities did not find the matching result in their databank, which has 70 million entries of adults.

Earlier, in the case of US Consulate suicide attack, police had found fingers of the suspected bomber and sent them to Nadra’s databank for his identification through matching the data. The Nadra system did not accept the fingerprints terming them ‘mutilated’. In case of Nishtar Park suicide bombing, the photo of the severed head of the alleged suicide bomber was sent to Nadra’s databank but no entry matching the severed head was found.
