They are: Maulawi Adam Khan Achekzai, Aamir Ali Chaudhry and Qari Ayyub Bashir. The Treasury Department said in a statement the three financially and materially supported known terror groups Tehrik-e Taliban Pakistan, or TTP, and the Islamic Movement of Uzbekistan, or IMU.
Adam is suspected of manufacturing and distributing improvised explosive devices for the Taliban in Afghanistan and Pakistan and was known to be the Taliban's shadow governor in two Afghan provinces and acted as a Taliban military commander, the Treasury Department said.
Chaudhry is an agent for TTP who advised the group on how to construct the bomb deployed in a failed attack on Times Square in New York in May 2010. He is believed to be operating in Pakistan's tribal areas.
Bashir is believed to be the IMU's money man, collecting and delivering donations for the group from across Europe and in Turkey. Additionally, in 2009 and 2010 he was a field operative for the IMU in Afghanistan working with Taliban forces, the department said.
"Today's actions are intended to disrupt the activities of three individuals working to carry out violent attacks in Afghanistan and Pakistan that threaten the lives of civilians and military forces." said David S Cohen, the Treasury Department's undersecretary for terrorism and financial intelligence.
"As these designations demonstrate, we will continue to work to dismantle the terrorist support networks operating in Afghanistan and Pakistan, paying special attention to those involved in the manufacture of IEDs."
