Russia’s U.N. ambassador alleged Monday that “neo-Nazis” and military-age men were at the wake for a Ukrainian soldier in a village café where a missile last week killed 52 people, even as Security Council members retorted that Russia was responsible for starting the war and committing crimes.

Vassily Nebenzia told a U.N. Security Council meeting called by Ukraine that the soldier was “a high-ranking Ukrainian nationalist,” with “a lot of neo-Nazi accomplices attending.”

In Thursday’s strike by a Russian Iskander ballistic missile, the village of Hroza in the northeastern Kharkiv region, lost over 15% of its 300 population. The café, which had reopened for the wake, was obliterated, and whole families perished.
