People walk past the scuttled decommissioned Russian vessel “Ochakov” on the Black Sea shore outside the town of Myrnyi, western Crimea, Ukraine, Thursday, March 6, 2014. In the early hours of Thursday Russian naval personnel scuttled the decommissioned ship, blockading access for five Ukrainian Naval vessels now trapped inside of the Southern Naval Headquarters located in Myrnyi in Western Crimea as Russian war vessels patrolled just of the coast. The vessel was brought by Russian naval forces on the 4th of March towed by a tug boat while escorted by a warship and several gun boats. Marines from the Ukrainian navy heard a loud explosion in the early hours of last night coming from the vessel blocking a channel leading to the Black Sea. (Photo by Darko Vojinovic/AP Photo)
