Ukraine said on Monday that 19 service members were killed by a Russian missile strike in Zaporizhzhia during a military awards ceremony in what President Volodymyr Zelensky said was a “tragedy that could’ve been avoided.” Defence Minister Rustem Umerov ordered an investigation into why the 128th Separate Mountain-Assault Brigade of Zakarpattia participated in the crowded event honoring troops close to front lines.

The announcement came as officials said Russian drone and missile strikes in Odesa wounded eight people and damaged an art museum that is part of a UNESCO World Heritage site, and satellite photos showed damage done by a Ukrainian missile strike to a Russian naval ship.
