The US has begun to squeeze the funding and flow of money to terrorist organisations in the Af-Pak region including the Taliban, al Qaeda, the Haqqani network and Laskhar-e-Taiba, and keeping a tab on hawala transactions. <br/> The U.S.Assistant Secretary for Terrorist Financing David Cohen said the US has identified countries in the Middle East as a major source of funding to extremists organisations in Afghanistan and Pakistan.<br/> To stem the flow of cash to terrorists, the US has set up an inter-agency task force headed by Treasury Department, which is monitoring appeals for funding by these groups all over the globe. Speaking at a Money Laundering Enforcement Conference, Mr.Cohen said working closely with Ambassador Richard Holbrooke, Treasury is deeply involved in the effort to deny financial support to Taliban, al Qaida, the Haqqani network, LeT and other terrorist groups active in that region.
