The Washington Post reported Tuesday that the Pentagon was moving parts of a THAAD system from South Korea to the Middle East, citing two U.S. officials.

Axar.az infroms, citing Korea Times, the reported redeployment of parts of the United States’ Terminal High Altitude Area Defense (THAAD) system from South Korea to the Middle East has raised questions about whether the move could affect missile defense readiness on the Korean Peninsula.

Military sources said six THAAD launcher vehicles that were recently moved from a base in Seongju, North Gyeongsang Province, to Osan Air Base in Pyeongtaek, Gyeonggi Province, have since returned to Seongju after unloading their interceptor missiles. The missiles are believed to remain at Osan and are expected to be transported to the Middle East aboard C-5 or C-17 U.S. military cargo aircraft.
