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.

A new ballistic missile fired by Russia at the Ukrainian city of Dnipro last week carried multiple warheads but no explosives, and caused limited damage, two senior Ukrainian government sources said.
