KARACHI - MQM chief Altaf Hussain has demanded of Chief Justice Iftikhar Chaudhry to order an inquiry into the whereabouts of 28 MQM workers who are missing since 1992 military operation. Thousands of MQM workers and their relatives were killed in the military operation launched in 1992 but no inquiry had been conducted into their brutal murders, Altaf Hussain said in his second open letter to the CJP on Thursday. He pointed out that before the inception of military operation in June 1992, Pakistan Army had issued and published a list of 72 bigwigs, who were providing protection to the criminals involved in heinous crimes. Chaudhry Nisar Ali Khan, PML-N now leader of the Opposition in the National Assembly had disclosed the names of those 72 persons but the operation was launched against the MQM workers. During military operation, as many as 28 workers of MQM were arrested in front of their family members but despite our appeals made umpteen times to the people at the helm of affairs, no one paid any attention, he recollected. Altaf Hussain further recalled that Chaudhry Shujaat Hussain made a statement in March 1998 on the floor of the Senate that all those missing MQM workers were murdered and then buried near Margalla hills in Islamabad. Altaf cited that Barrister Farooq Hasan had lodged a formal constitutional petition in 1994 for an inquiry into the massacre but authorities concerned turned a deaf ear to that complaint. Please take some of your precious moments out of your hectic schedule and meet personally with family members and relatives of all those missing MQM workers in order to get firsthand account of their arrests. It would enable to personally observe the plight of the family members of all those workers who went missing, he appealed. The MQM chief also demanded of the Chief Justice to take appropriate action by ordering the government to conduct a thorough inquiry so that not only the parents and family members of all those missing workers could heave a sigh of relief but the elements responsible for such an inhuman act could be brought to justice.
