"Thirteen of the occupiers' cruise missiles were destroyed on June 23... This time, the attack was aimed at a military airfield in the Khmelnytskyi region," the Ukrainian air force said on social media.

Russia launched waves of aerial attacks with cruise missiles and attack drones over the winter, prompting Kyiv to appeal to its Western allies to bolster its air defence systems.

"The launches were carried out around midnight from the Caspian Sea from four Tu-95MS bombers," the air force statement said.

The mayor of Khmelnytskyi Oleksandr Symchyshyn reported explosions in the town with a pre-war population of around 275,000 and praised Ukrainian air defence systems.

Ukraine also said that it had shot down a Russian reconnaissance drone overnight.

The Russian defence ministry later released a statement saying its forces had targeted Ukrainian weapons depots with long-range precision strikes and that "all assigned targets were hit".
