Ukrainian forces likely launched a strike within Donetsk using a newly supplied, long-range missile with a 550-kilometer range, according to Ukrainian media reports. The missile is believed to have been secretly provided by the United States. This marks the first reported use of this weapon by Ukraine against Russian-held territory in Donetsk. Reports suggest the US may have provided the missile to test its capabilities in a real-world combat environment. The strike represents a potential escalation in the conflict and a demonstration of Ukraine's expanding military reach. Details surrounding the attack and any resulting damage remain limited, but the event highlights continued US support for Ukraine. This assistance allows Ukraine to target locations previously beyond their reach.
