US accuses Russia of nuclear sabre-rattling, amid Nato tensions


US Defence Secretary Ash Carter has accused Russia of "nuclear sabre-rattling" and of being intent on eroding international order.

He said he regretted strained relations with Moscow but said the US had to "prioritise deterrence" on Nato's eastern flank.

US-Russian ties have been strained by the Ukraine crisis and recent military encounters in the Baltic Sea.

Speaking during a ceremony at the US European Command Headquarters in Germany, Carter said Russia was "going backwards in time", but added that they do not seek a cold, let alone a hot war with Russia.
