Thirty members of Ukraine's volunteer battalion Pravyi Sektor (Right Sector) have taken up residence a few kilometers from the Donetsk airport in the village of Pisky. The Donetsk airport has become a major flashpoint in the Russian war against Ukraine. The area around the now-destroyed transportation hub is regularly the site of gun battles between the Ukrainian fighting forces and Kremlin-backed separatists. The government forces try to prevent Russians from using the runways to land transport planes loaded with armaments. Some say they need to defend the airport as a sign of resolve against Russian aggression.
