Two senior leaders of Muttahida Qaumi Movement (MQM) were arrested Saturday for unknown reasons minutes before they were scheduled to address mediapersons at the Press Club in Karachi.

A heavy contingent of the paramilitary Rangers surrounded the Karachi Press Club and arrested the two leaders of the new coordination committee formed by the Altaf Hussain-led London-based MQM.

The incident marks another crackdown against the MQM by the Rangers.

According to Pakistani media reports, Hussain called Pakistan under the Nawaz Sharif administration a cancer of the world and an epicentre of global terrorism.

MQM is a political party representing the Urdu speaking Mohajirs in Sindh. It remains the single largest party in Karachi for decades now and have dominated the political landscape of Pakistan’s largest city for years, sweeping provincial and national elections.
