Russia deploys new S-400 missile systems in Crimea

Russia on Thursday deployed a new battalion of advanced S-400 surface-to-air missile systems in Crimea, its fourth such battalion, the TASS news agency cited a spokesman for Russia's Black Sea Fleet as saying.

The new battalion had been deployed in Djankoy in northern Crimea, the spokesman said.

News of the new deployment in Crimea, which Russia annexed from Ukraine in 2014, follows Russia's seizure of three Ukrainian navy vessels off the coast of the peninsula on Sunday.
