The new US sanctions apply to Brigadier Gen. Ko Ko Oo, and Major Gen. Zaw Hein, as well as the 66th Light Infantry Division, which the Treasury said had been accused of carrying out a December 2021 massacre in which civilians “were captured, tortured and killed, including some whom members of the military reportedly burned alive.”

Three individuals and two companies were also sanctioned for providing arms to the military, while two firms were targeted for assisting other businesses that had been sanctioned previously.

The UK sanctioned Htun Aung, commander in chief of the Myanmar Air Force, and a company that supports the air force, along with Belarusian Honorary Consul Aung Moe Myint and his company.

They also joined Washington in sanctioning a businessman and his company that the countries said trafficked arms.
