Missile tests are a success, official says

Russia tested new missiles that First Deputy Prime Minister Sergei Ivanov boasted could penetrate any defense system.

Ivanov said Russia tested an intercontinental ballistic missile capable of carrying multiple warheads, and successfully conducted a "preliminary" test of a cruise missile with an extended range. The former defense minister is seen as a potential successor to President Vladimir V. Putin.

Russia has bristled at U.S. plans to deploy a missile defense system in Poland and the Czech Republic.

It dismisses U.S. assertions that the system would aim to block possible attacks by Iran and says it would destroy the balance of forces in Europe.
