 The United States has played down reports that American-made military hardware was used in a cross-border raid from Ukraine into Russia, after Moscow released footage from the area showing damaged vehicles, including at least two Humvees. Russia said on May 23 it had repelled the two-day attack in southwestern Belgorod region, killing more than 70 Ukrainian fighters and destroying four armored vehicles and five pickup trucks. The incursion was the largest into Russian territory from Ukraine since the start of the full-scale invasion 15 months ago. Ukraine denied any role in the raid, which has been claimed by two anti-Kremlin-armed groups made up of Russian nationals fighting for Ukraine against their compatriots. They include far-right figures among their leadership.
