The United States has expressed concerns about Mumbai terror attacks mastermind Hafiz Saeed running for office in Pakistan next year. The Jamaat-ud-Dawah Chief had earlier said, his organisation will contest the general elections under the banner of the Milli Muslim League, which is yet to be registered with the Election Commission. <br/><br/>US State Department spokesperson Heather Nauert told reporters in Washington that Saeed is a United Nations and a US-designated terrorist. She said the JuD Chief's release by Pakistan from house arrest last month and now reports of him running for office is a matter of concern for Washington. <br/><br/>Saying that the US has had many conversations with the Pakistan Government, Ms Nauert hoped that Islamabad will do the right thing. She reiterated that there is a 10 million dollar reward for information that would bring Saeed to justice.
