Ukraine's defense minister, Rustem Umerov, has ordered an investigation into an alleged Russian ballistic missile attack on a Ukrainian assault brigade during an award ceremony. While the exact number of casualties is unclear, reports suggest that at least 20 soldiers were killed in the attack that took place in the Zaporizhzhia region. The Ukrainian Armed Forces stated that Russia used the Iskander ballistic missile to attack the brigade and that local residents were also injured. The Russian Defense Ministry acknowledged that they "inflicted fire" on a unit of Ukraine's assault brigade, but did not provide casualty figures. Ukrainian President Volodymyr Zelensky expressed his condolences and declared the incident a "tragedy that could have been avoided." He announced that a criminal investigation has been launched into the attack. The Ukrainian army has not independently verified the reports of casualties. The investigation will aim to determine the circumstances and exact location of the attack, as well as the number of casualties. The attack has further escalated tensions between Ukraine and Russia, who have been engaged in a 20-month-long war.
