Russia’s Defense Ministry has denied reports that one of its missiles hit a residential building in Kiev, saying the damage was caused by a Ukrainian anti-aircraft projectile, Russian news agencies reported on Saturday, citing a source at the ministry.

“The reports on social media about a Russian missile attack on a residential building on Lobanovsky Avenue in Kyiv are not true,” the Defense Ministry source said, according to TASS and RIA Novosti. “The nature of the damage to the house indicates that an anti-aircraft missile hit it. This is clearly visible on the video.

“Obviously, during the fight against a night rocket attack on military infrastructure … of Ukraine, a failure occurred in the missile guidance system of the Ukrainian medium-range air defense system Buk -M1, and the missile hit the corner of a residential building,” the source added, according to TASS and RIA Novosti.
