NATO members on Tuesday reaffirmed their support for Ukraine during talks with the country's officials held in response to Russia's launch of an experimental intermediate-range ballistic missile last week.

This is the first time Russia has used its so-called Oreshnik intermediate-range ballistic missile in combat. The launch also serves as a warning to the West.

Ukraine fired five of the U.S.-made long-range missiles on Saturday, targeting an S-400 battalion near Lotarevka, northwest of Kursk, Russia’s Defense Ministry said. Two of projectiles hit their targets, damaging a radar and resulting in casualties, according to the statement.
