Kyiv’s historic Cave Monastery, a UNESCO World Heritage site, sustained significant damage following a reported attack early Monday morning. Director Maksym Ostapenko estimates reconstruction could take up to two years, with over 80% of the 11th-century cathedral destroyed by fire. Ukraine alleges a deliberate Russian strike, while Russia denies involvement, claiming damage resulted from a U.S.-made Patriot missile. The attack resulted in nine fatalities. The monastery, a significant cultural and religious landmark, now faces an extensive restoration process. The incident has sparked international concern regarding the protection of Ukraine’s cultural heritage during the ongoing conflict. Investigations are underway to determine the exact cause of the damage.
