Ukraine carried out a military strike on a Russian arms depot used to store North Korean missiles over the weekend, according to Kyiv, though one expert said the claim should be taken with a grain of salt in the absence of concrete evidence.

The attack on Sunday targeted a munitions warehouse in the village of Soldatskoye of the Voronezh region, less than 80 miles from the Ukrainian border, the head of Ukraine’s Center for Countering Disinformation Andrii Kovalenko announced on his Telegram channel.
