Crimean Tatars clash with police
Police explained they tried to restore traffic when seven of their officers received minor injuries. Four protestors were detained.
Tensions between ethnic Tatars, Ukrainians and Russians persist in Crimea.
Soviet leader Josef Stalin deported 200,000 Crimean Tatars to Central Asia in 1944, accusing them of collaboration with the Nazis during World War Two.
Many have returned after the collapse of the Soviet Union in 1991 and are now seeking to regain ownership of their property, which results in clashes with other residents.
