Hussain, who is living in self-exile in London, said this in an address to his party supporters who were holding a protest march against Pakistani Army in front of the White House on Saturday, a media release said.
In his address, Hussain said the injustices being perpetratedby the Pakistan Army and Rangers against members and supporters of MQM threaten the lives of fellow Mohajirs each and every day.
"Since 2013, the Pakistani military has imposed effective martial law on our city. And for the duration of this so-called operation, Paramilitary soldiers have roamed our streets, unaccountable to civil authorities," he alleged.
As per a Lahore High court ruling, the Pakistani media has been asked not to display his photograph.
Hussain urged the Obama administration to use their good offices to press Pakistani establishment to cease its attacks on MQM, respect the rule of law and the democratic will of the people.
