Former premier Benazir BhuttoÂ’s lawyer Farooq Naek said on Friday the investigation into the October 18 blasts in Karachi was directionless and the investigators hadnÂ’t questioned any of the suspects that her client had mentioned in a letter sent to the president, a private channel reported. According to Geo television, Naek said it was a duty of the investigators to question the suspects irrespective of their status. Naek said foreign investigators should be asked for assistance, much like Bhutto had done for the probe into her brother Murtaza BhuttoÂ’s murder during her tenure as prime minister. Naek said Punjab Chief Minister Chaudhry Pervaiz Elahi should be investigated, since Bhutto mentioned his name in her list of suspects. Meanwhile, Federal Railways Minister Sheikh Rashid Ahmad told Geo television that the Pakistan PeopleÂ’s Party workers that died in the Karachi blasts were martyrs and Bhutto should pay the affected families Rs 10 million each, instead of just Rs 5,000. He said many people had returned the Rs 5,000.
