Moscow : Russian President Vladimir Putin, on Sunday ordered border security to ensure 'fast' Russian military and civilian movement into Ukrainian regions that are now under the control of Moscow, TASS, a Russian News Agency reported.

In his address on the occasion of Border Guards Day, Putin said, "Securing the border in close proximity to the field of operations is a separate and very important task. At the same time, it is vitally important to ensure fast movement of both military and civil vehicles and cargo, including food, humanitarian aid, and construction materials on their way to new constituent entities of the Russian Federation - the Donetsk and Lugansk people's republics, and the Zaporizhia and Kherson regions." Putin also noted the necessity of close cooperation between border guards and other units of the Federal Security Service, the Armed Forces and the National Guard of the Russian Federation, as well as regional government bodies, reported TASS.

"I have great confidence in you, your professionalism and bravery, and know that you will do everything in your power to securely protect our Motherland's borders from any threat," Putin emphasized.
