Russia's troops have seized control of a naval base near Crimea's city of Feodosia, Novinite reports. 

Over the past 48 hours, this was the third successful Russian assault of a Ukrainian base on the Crimean peninsula.

It leaves all Ukrainian bases in the region, which was incorporated into the Russian Federation last week, under control by Moscow. Belbek airbase to the south of Crimea was also taken over on Saturday, with its commander, Colonel Yuli Mamchur, reportedly missing.

Russian defense officials quoted by the BBC have declared that Russia's flag is now waving at 189 military units and facilities across Crimea.

Last week, the EU and the US imposed sanctions to Russian and Crimean officials over the standoff on the Crimean peninsula, which officially broke away from Ukraine to become part of Russia.
