Russia is sending two battalions of S-400 surface-to-air missile systems to Belarus to join military drills there next month, the Interfax news agency said on Friday, at a time of acute tensions with the West over neighbouring Ukraine.
Russian military forces and hardware began arriving in Belarus this week for the "Allied Resolve" drills to be held near the former Soviet republic's western border with NATO members Poland and Lithuania, and close to its southern flank with Ukraine.
