A top Russian general says Moscow will take adequate measures to counter U.S. missile defense plans.

Lt. Gen. Yevgeny Buzhinsky told a Tuesday briefing that Russia was thinking about "asymmetrical" steps if the United States deploys missile defense elements in Europe. He did not give specifics.

At the same time, Buzhinsky said that the military doesn't plan to beef up the Soviet-era missile defense system that protects Moscow.

Russia has rejected the U.S. assurances that the plans were designed to counter a missile threat from Iran. It says the U.S. missile defense facilities will undermine its security.
