MQM did massive rigging in Karachi and now Altaf hussain is openly threatening PTI and other parties who are complaining about the rigging in Karachi. This is very immature and cruel behaviour by MQM. People are now becoming increasingly sure that MQM is promoting terrorism as is evident from his threatening speech. He even talked about the separation of Karachi from the rest of Pakistan. What kind of his leader is he? Very frustrating.
