Aug. 3 (Asia Today) -- South Korea's Defense Ministry relieved the commander of the Army's I Corps of his duties Monday amid investigations into unloaded weapons at front-line posts and the military's mistaken identification of a U.S. Marine Corps drone.

The ministry said Lt. Gen. Han Ki-sung was suspended from duty effective Monday while inspections and investigations involving the corps continue.

The commander of the Army Training and Doctrine Command will serve as acting corps commander during Han's suspension, the ministry said.

The action followed controversies over changes to border security procedures and a failure to share information about a U.S. military drone flight through the South Korean chain of command.
