Top Russian security official Nikolai Patrushev said on Wednesday that "Ukrainian special services" were behind last month's deadly concert shooting near Moscow and that Ukraine was under the control of the United States, state media reported.
Patrushev, secretary of the Security Council, provided no evidence for Russia's latest claim of Ukrainian involvement. Ukraine has denied having anything to do with the attack that killed at least 144 people, and the United States has said Islamic State militants bore sole responsibility.
