The recent Russian air strike on the Ukrainian city of Dnipro has raised alarms due to the characteristics of the missile used, named Oreshnik. Russian President Vladimir Putin claims it operates at Mach 10, while Ukrainian officials contend it is an advanced intercontinental ballistic missile. Analysts suggest that its development could place much of Europe within range, but not the US. Experts are debating its true capabilities and origin, highlighting growing concerns about missile defense amid escalating tensions.
