The PPP leader Dr Zulfiqar Mirza made a scathing criticism of both the MQM and Interior Minister Rehman Malik at a press conference he especially called at Karachi on Sunday to tell, according to him, the truth behind the carnage daily taking place in Karachi. In unambiguous terms and without the slightest hesitation whatsoever, he put the entire blame on them. It was virtually a charge-sheet. Dr Mirza, who had earlier also been highly critical of the MQM for its role in disturbing the peace in Karachi, had some months back to leave the portfolio of Sindh Home Ministry in order to placate the MQM. In its place, he was given the assignment of Senior Minister in the provincial cabinet. He announced before the media his resignation not only from this office, but also from the Sindh Assembly seat and as Senior Vice President of the PPP Sindh; in fact, he declared that he was leaving politics, though ideologically remaining a staunch supporter of the party and would henceforth devote himself to work for restoring peace in Karachi. Dr Mirza openly and repeatedly declared that Mr Malik was the single most threat to Pakistan, who had no stake in the country, and was hand in glove with the killers, bitterly opposing his interference in the law and order situation in the city. To the MQMs share of blames also came as serious allegations as involvement in an attempt to break up Pakistan at the instance of the US, and trying to persuade Britain to work for the winding up of the Pakistan armys premier intelligence agency, the ISI. While other charges, as grave as they were, made by Dr Mirza against the MQM are of internal relevance and need internal remedies, these two the attempts at the countrys dismemberment and bringing the institution of ISI to an end call for an impartial probe. Needless to question the suggestion made by some opposition leaders that a judicial commission should be constituted without any delay to look into the allegations, particularly relating to these two aspects and lay the factual picture before the public. Whatever Dr Mirza said he said on oath either with the Quran on his head or his hand on the holy book and in full view of the world; for hardly was there any local TV channel which did not broadcast his press conference in full lasting for nearly two hours, to the utter shock and consternation of the viewers. His revelations would have far-reaching and serious implications for Pakistan. Mr Rehman Maliks 'denial simply through the remarks that he was a younger brother and if he had any proof he should come out with it, would not do. As with him, the MQM would also have to deny the charges on Quranic oath; only then the public could lend any credibility to their versions. Words like absurd, obnoxious and ludicrous are not sufficient. The government must also step in with its own version based on hard facts and work on that basis to bring peace to Karachi.
