A gunman killed six people and wounded at least 14 others in a mass shooting in Kyiv before police shot and killed the attacker, according to reporting by NPR.

The shooting occurred in Ukraine's capital city, adding a domestic public safety crisis to a country already enduring more than two years of full-scale war with Russia.

Ukrainian police intervened and fatally shot the gunman, bringing the attack to an end. Authorities have not publicly identified the shooter or detailed a motive as of the time of reporting.

The incident marks one of the deadliest mass shootings in Ukraine's recent history unrelated to the ongoing armed conflict with Russian forces. Kyiv, while frequently targeted by Russian missile and drone strikes, has largely been shielded from ground-level violence of this kind.

Details surrounding the circumstances of the attack - including the location within the city, the weapon or weapons used, and any possible connection to the broader war - had not been fully confirmed at the time of publication.

Ukrainian authorities were continuing their investigation into the shooting. Further information was expected to be released as the inquiry progressed.

The attack drew attention both domestically and internationally, given Ukraine's position at the center of a major European conflict. Mass casualty events of this nature are relatively rare in the Ukrainian capital, which has a population of several million people.

NPR reported the story citing available information from Ukrainian officials and emergency services. The full scope of the investigation, including any potential charges or background on the attacker, remained pending.
