Russia claims it has struck six railway hubs in the West of the country.
Russian troops destroyed six traction substations, units that power the railways that are being used for delivery of foreign weapons and military hardware to Ukrainian forces in the Donbass, Defense Ministry spokesman Major General Igor Konashenkov announced on Monday.
He said the stations were located in Krasnoye, Zdolbunov, Zhmerinka, Berdichev, Kovel and Korosten railway hubs, all in western Ukraine.
Konashenkov said that 27 military targets were destroyed by air strikes, including four command centers.
Defense Minister Sergey Shoigu said last month that pushing Ukrainian troops from the territory of the Donbass republics had become Moscow's top priority at this stage of the campaign.
Ukraine s Western backers have not revealed the exact routes they use to ship weapons to Kiev, but reports say that many of them are being delivered through neighboring Poland.
NATO member states supply various anti-tank and anti-aircraft missile systems, armored vehicles, howitzers, and other weapons to Kiev. US Defense Secretary Lloyd Austin and Secretary of State Antony Blinken traveled to Ukraine on Sunday, where they promised additional military aid to President Volodymyr Zelensky.
In late February, Russia attacked the neighboring state, after Ukraine failed to implement the terms of the Minsk agreements, first signed in 2014, and Moscow s eventual recognition of the Donbass republics of Donetsk and Lugansk. The German and French brokered protocols were designed to give the breakaway regions special status within the Ukrainian state.
The Kremlin has demanded that Ukraine officially declare itself a neutral country that will never join the US-led NATO military bloc. Kiev insists that the Russian offensive was unprovoked and has denied it plans to retake the two republics by force.
