MOSCOW, July 8 (Xinhua) — Russia's Arms Committee at the Russian Federation Council, or the upper parliament house, on Friday warned that missile units could be deployed in eastern Russia in response to the deployment of the U.S. missile defense system called Terminal High Altitude Area Defense (THAAD) in South Korea.

According to deputy chairman Evgeny Serebrennikov, the committee would work out certain decisions together with the Defense Ministry on military planning including deployment of missile and ground units, so as to counter the influence of the United States deploying its missile defense system in South Korea.

"We will take into consideration the decision on deployment of U.S. missile defense in South Korea for our military planning," Serebrennikov was quoted by RIA Novosti news agency as saying.

"In cooperation with the defense ministry we will work out certain decisions on strengthening of influence in this direction, including through deployment of missile and ground units," he added.

Earlier in the day, South Korea and the United States announced their final decision to deploy the THAAD in the U.S. Forces Korea (USFK) stationed on the Korean peninsula to tackle the Democratic People's Republic of Korea's nuclear and missile threats.
