Russia is denying responsibility after damage was reported at the Qatari Embassy in Kyiv during one of the largest aerial assaults in months. Moscow insists its forces did not target diplomatic missions and claims the damage was caused by a malfunctioning Ukrainian air defence interceptor that went off course. Russian officials say Qatar remains a “priority partner” and a “friendly state.” Ukraine strongly disputes that account. President Volodymyr Zelensky says the embassy was damaged amid a massive overnight barrage involving an Oreshnik hypersonic missile, more than 200 drones, and multiple cruise missiles fired across the country. Kyiv has highlighted Qatar’s role as a mediator in prisoner exchanges, calling the incident a dangerous diplomatic escalation. Russia confirms it carried out large-scale strikes but says the operation targeted Ukraine’s energy infrastructure and drone production facilities, framing the attacks as retaliation for an alleged strike on the Russian president’s residence in the Novgorod region. Qatar has expressed regret over the damage to its embassy but stopped short of naming Russia, while the Gulf Cooperation Council and several Arab states voiced concern without assigning blame.
