KYIV, Ukraine — Russia’s military said Tuesday it quashed what appeared to be one of the most serious cross-border attacks from Ukraine since the war began, claiming to have killed more than 70 attackers in a battle that lasted around 24 hours.
Moscow blamed the raid that began Monday on Ukrainian military saboteurs. Kyiv portrayed it as an uprising against the Kremlin by Russian partisans. It was impossible to reconcile the two versions, to say with certainty who was behind the attack or to ascertain its aims.
The battle — which took place in southwest Russia’s Belgorod region, about 80 kilometers (45 miles) north of the city of Kharkiv, in eastern Ukraine — was a fresh reminder of how Russia itself remains vulnerable to attack, along with Russian-occupied regions of Ukraine.
The region is a Russian military hub holding fuel and ammunition depots and was included in Russian President Vladimir Putin’s order last year to increase the state of readiness for attacks and improve defenses.
Kremlin spokesman Dmitry Peskov refused to say how many attackers were involved in the assault or comment on why efforts to put down the attackers took so long.
