Russia launched an experimental hypersonic intermediate-range ballistic missile at Dnipro, Ukraine, escalating tensions amid Ukraine’s use of U.S. and UK missiles to strike Russian territory, according to Reuters. Russian President Vladimir Putin said the missile targeted a Ukrainian military facility and warned of further strikes. A U.S. official, speaking on condition of anonymity, said Russia likely possesses a handful of the "experimental" intermediate-range ballistic missiles used in Thursday's strike. Hostilities have intensified as Ukraine fired British and U.S. missiles at Russian targets, which Moscow called major escalations.
