Which Country labeled U.S. troops in West Asia as 'terrorist'?

Iran's lawmakers approved a bill labeling U.S. forces in West Asia (Middle East) as terrorist. This move comes a day after the U.S. terrorism designation for Iran's Revolutionary Guard formally took effect. Iran's Defense Minister Gen. Amir Hatami introduced the bill authorizing the government to act firmly in response to terrorist actions by U.S. forces. It demands authorities use legal, political and diplomatic measures to neutralize the American move, without elaborating. The U.S. move aims at thwarting Iran's influence and shows that America's longstanding sanctions against Iran have become ineffective.
