Ukraine military carries out exercises amid Russia tensions

The Ukrainian military carries out exercises in the town of Urzuf, between the ports of Berdyansk and Mariupol amid high tensions with Russia. Moscow and Kiev have traded angry accusations since Russian navy vessels fired on, boarded and captured the three Ukrainian ships. Poroshenko has signed an act imposing martial law for 30 days in regions bordering Russia, the Black Sea and the Sea of Azov. IMAGES
