Russia’s Defense Ministry denies responsibility for damaging the Kyiv Pechersk Lavra monastery complex and instead attributes the incident to a possible malfunction involving a US-made Patriot air-defense missile. In statements accompanying reports of a large overnight strike across Ukraine, Moscow says it did not carry out the strike that affected the monastery. Both accounts describe the same position: Russia claims the missile involved in the episode may have fired incorrectly. According to the ministry, one possible reason is that Western countries supplied Kyiv with Patriot missiles whose service life had expired. The ministry points to the expiration dates of the missiles as a factor that could lead to incorrect operation. Other details about the overall overnight strike and the specific targeting elements are referenced, but the core claim across sources is that Russia contests the allegation of direct involvement and offers a technical explanation centered on the reliability of supplied Patriot munitions. The reports reflect Russia’s official explanation and do not confirm independently the cause of the damage.
