paragraph_text: Russian military bases in Crimea
  
  When the Russian occupation of Crimea began, Russia had roughly 12,000 military personnel from the Black Sea Fleet, in several locations in the Crimean peninsula such as Sevastopol, Kacha, Hvardiiske, Simferopol Raion, Sarych, and others. In 2005 a dispute broke out between Russia and Ukraine over control of the Sarych cape lighthouse near Yalta, and a number of other beacons. Russian presence was allowed by the basing and transit agreement with Ukraine. Under this agreement, the Russian military in Crimea was constrained to a maximum of 25,000 troops. Russia was required to respect the sovereignty of Ukraine, honor its legislation, not interfere in the internal affairs of the country, and show their "military identification cards" when crossing the international border. Early in the conflict, the agreement's generous troop limit allowed Russia to significantly strengthen its military presence, deploy special forces and other required capabilities to conduct the operation in Crimea, under the pretext of addressing security concerns.
  
  According to the original treaty on the division of the Soviet Black Sea Fleet signed in 1997, Russia was allowed to have its military bases in Crimea until 2017, after which it would evacuate all military units including its portion of the Black Sea Fleet from the Autonomous Republic of Crimea and Sevastopol. On 21 April 2010, former Ukrainian president Viktor Yanukovych signed a new deal with Russia, known as the Kharkiv Pact, to resolve the 2009 Russia–Ukraine gas dispute. The pact extended Russia's stay in Crimea to 2042, with an option to renew.
