Dozens killed as Russian air strikes hit Ukrainian military base near Polish border

Dr Jack Watling, a Royal United Services Institute research fellow in land warfare, said staff at the training centre would have become accustomed to moving military hardware sent into Ukraine from outside the country." The Russians want to reinforce the point that they see international forces on Ukrainian soil as a red line," he said. "So it makes sense that they struck the base, firstly in order to attempt to disrupt the movement of material into Ukraine, secondly to demonstrate to the international community that there is nowhere in Ukraine that will not be targeted and thirdly because it's likely a base where where there were individuals used to the paperwork and bureaucracy of moving defence material in and out of the country.
