US has imposed sanctions on Pakistan-based extremists and an organisation run by Mumbai attack mastermind Hafiz Saeed's Jamaat-ud-Dawah (JuD) group. <br/><br/>Director of Treasury's Office of Foreign Assets Control, John Smith said the sanctions seek to disrupt the financial support networks of terrorists who have provided support to the Lashkar-e-Taiba, Jamaat-ul-Dawa al-Qu'ran, Taliban, al-Qaeda and Islamic State terror group, for recruitment and funding of suicide bombers and other violent insurgent operations. <br/><br/><br/>Mr Smith said, the US continues to aggressively target extremists in Pakistan and the surrounding region, including charities and other front groups used as vehicles to facilitate illicit terrorist activities.<br/><br/>During a Congressional hearing on Worldwide threats, Director of National Intelligence, Daniel Coats, told members of the Senate Select Committee on Intelligence that Islamabad has failed to curb militants and terrorists in Pakistan. He said these groups will present a sustained threat to the United States's interest in the region and continue to plan and conduct attacks in India and Afghanistan.<br/>
