Two men walk along an embankment of Sevastopol Bay with the Monument to the sunken ships during a celebration of the Navy Day usually very crowded in Sevastopol, Crimea. Authorities say a small explosive device carried by a makeshift drone blew up Sunday at the headquarters of Russia's Black Sea Fleet on the Crimean Peninsula, wounding six people. The attack prompted the cancellation of ceremonies honoring Russia's navy there. (AP Photo)
