MOSCOW (Reuters) - Russia has deployed its advanced S-400 air defence missile system to annexed Crimea, Russian news agencies reported on Friday, citing a statement from the Russian Defence Ministry.

The announcement comes two days after President Vladimir Putin promised to take counter-measures after what he said were clashes between Russian forces and Ukrainian saboteurs in northern Crimea.
