Russia is planning to test-fire two more intercontinental ballistic missiles later this month, a move that could raise regional tensions after a similar launch on Tuesday.
Moscow submitted requests for three tests to the government of neighboring Kazakhstan on Feb. 19, which were approved on Feb. 28, according to a statement on the Kazakh defense ministry's website.
On Tuesday, a Topol intercontinental ballistic missile was fired from a launch pad in southern Russia that hit a designated target on a range leased by Moscow from Kazakhstan.
A senior U.S. official told NBC News that the test launch had been "on the books for some time prior to the current crisis in Ukraine."
