The Kremlin has pledged to “retaliate” after reportedly shooting down eight American-made long-range missiles at the start of the new year. According to Russian officials, Ukraine deployed Army Tactical Missile Systems (ATACMs) targeting positions roughly 25 miles north of the border in the Belgorod Oblast.

Russia has vowed retaliation after claiming to have shot down eight US-made ATACMS missiles fired by Ukraine on Saturday morning. Moscow sees the use of such missiles, which have a range of up to 300 kilometers (186 miles) as a major escalation.
