Ukraine said on Saturday it had hit two Russian munition depots overnight, in attacks that illustrated its growing capability to strike targets deep inside Russia. A statement by Ukraine's military general staff said the munitions depots were at Tikhoretsk in southern Russia and Oktyabrsky in the western region of Tver.

When Ukraine began a major campaign of strikes against Russian oil and gas facilities nine months ago, its goals were clear: to hurt Russia's wallet and disrupt the infrastructure used to fuel Moscow's invasion.
