Karachi- Muttahida Qaumi Movement (MQM) leader Faisal Sabzwari said today that the Protection of Pakistan Ordinance (PPO) is a draconian law and it has started showing its effects. Sabzwari said that six of his party workers went missing and might have been killed by the agencies. “The Sindh government must tell us about our party workers as it is responsible for them,” he said. PPO has been criticized bitterly by the MQM as well as other parties.
