Nearly a week ago, mainly christian people of the Essa Nagri were protesting on the main Sir Shah Suleman Road around 11 pm. While they were throwing stones and burning tyres the cars and other vehicles stopped just before the place. Meanwhile some armed opportuninits came from the streets around the area and looted the people stucked on the road by taking their mobiles and other valuables and forced them to leave their cars.
That sounds like the work of the MQM.
