Police said on Friday there were “developments” in the investigation into last week’s suicide attack against Benazir Bhutto but warned that continued criticism from the former prime minister could hamper their progress, AP quoted Karachi Police Chief Azhar Farooqi as saying. Farooqi said his force had solved every suicide attack they had looked into. “We are pretty hopeful we can work it out,” he said. He said they have released sketches of two men thought to be the suicide bombers who devastated Bhutto’s rally.
