The United States on Tuesday offered a reward of up to $3 million for information about a former Tajik special operations colonel whom it trained in counter-terrorism before he joined Daesh ‘ISIS’.

The U.S. State Department announced the reward for Gulmurod Khalimov in a statement that made no mention of his training, which included attending five U.S.-funded courses in the United States and Tajikistan between 2003 and 2014, said a U.S. State Department official who spoke on condition of anonymity.

The statement described Khalimov as “a key leader” of Daesh, or the Islamic State militant group, also known as ISIL and ISIS, that has seized parts of Syria and Iran and staged or inspired attacks around the world.

“Khalimov is a former Tajik special operations colonel, police commander, and military sniper. He was the commander of a police special operations unit in the Ministry of Interior of Tajikistan. He is now a Daesh member and recruiter,” it said.
