@Lordyaswas,
From Wiki.......
"The Russian Black Sea Fleet's use of leased facilities in Sevastopol and the Crimea has been controversial. A number of incidents have taken place:
A lighthouse is located on the headland, which from 2005, was the subject of a controversy between Ukraine and Russia. From August 3, 2005, the lighthouse is occupied by the Russian Army.[45] Not paying attention to the ruling of the Government Court in Sevastopol on the subject of the return of 77 geographical objects to Ukraine (including the lighthouse on Sarych), Russian military officials referred to the fact that they only subordinate to the chief of the Russian Navy headquarters and no one else. The Ukrainian public activists state that Sarych is illegally occupied by the Russian Navy.[46] As a military object, the territory around the Sarych headland is closed to trespassers with barbed wire with the Russian flag flying above Sarych.[47]
In 2006, Ukrainian officials prevented Russian workers from entering the Black Sea Fleet lighthouse in Yalta.[citation needed]
During the 2008 South Ossetia War, the Ukrainian Navy was ordered to block the entrance of Russian vessels taking part in hostilities to Sevastopol.[48] However, Russian Navy ships returned to base unimpeded.
June 20, 2009 – In Sevastopol, an incident again took place involving the Black Sea Fleet. In 2007, the administration of this organization was contracted by some 200 citizens of Sevastopol to build four several stories residential buildings. The job was never finished although the financial aspect of the contract was fulfilled as it was a prepaid venture. At this time, there are only two buildings that are only finished at 95% as stated in the local newspaper Novyi Sevastopol. The protesters are being simply kicked out by force without any intention to regulate the conflict. The protesters also sent a letters to the President and the Prime-Minister of the Russian Federation, Dmitry Medvedev and Vladimir Putin, and also to the Minister of Defense of Russia, Anatoliy Serdyukov. Those attempts brought no results. UNIAN
On August 27, 2009, Ukrainians identifying themselves as bailiffs were detained when they attempted to seize a Russian lighthouse. Russia states that Ukrainians may not step onto its bases without permission.[49]
On April 16, 2013 a "high-ranking Russian Defense Ministry official" complained to Interfax that “Ukraine’s stubborn position" was slowing the cancellation of customs payments (for the fleet) and that Ukraine still upheld (former) Ukrainian President Viktor Yushchenko 2008 decrees that banned the "relaxed procedure" of Black Sea Fleet formations across the Ukrainian border.[11]........"
