ISLAMABAD (NNI) - Paying tributes to Mir Murtaz Bhutto on his death anniversary falling today (Tuesday), President Asif Ali Zardari has said that he will be remembered for refusing to give up opposition to dictatorship despite suffering grievously for it. The killers of Murataza would not escape punishment and they would be exposed and punished as the wheels of justice grind invisibly, Mr Zardari said in his message. He said many people believe that Murtazas murder was part of a conspiracy to overthrow the PPP government. He (Murtaza) endured the agony and uncertainty of exile and the assassination of his brother and father that would have crippled many but Murtaza endured it with courage and fortitude, the President said. The President also prayed for the soul of Murtaza and those killed with him. May Allah grant patience to their heirs to bear this heavy loss, he said.
