HUR claimed Russian forces suffered losses among the personnel, without providing any further details. There were no losses among the Ukrainian forces, it said.

An incursion into Russia could be an attempt by Kyiv to divert Russian resources elsewhere. Given the spate of more negative developments from the frontline, the news of a successful incursion help Kyiv boost the morale of its troops and civilian population.

It could also be a message to Russia’s civilian population – a demonstration that Moscow’s war on Ukraine makes Russia vulnerable to attacks.

A Russian military blogger Rybar reported on Wednesday that the Ukrainian military had established control over a gas transit station near the border. The blogger said the station is the only one through which gas from Russia flows to Ukraine and then to Europe. CNN cannot confirm that reporting.

The European Union has imposed wide-ranging economic sanctions on Russia – with the exception of key natural gas imports. The EU was dependent on Russian gas and while it has slashed imports from Russia from 45% of all gas imports in 2021, to 15% of EU gas imports in 2023, some Russian gas still continues to flow to Europe through Ukraine, despite the war.
