Tanks move away from Ukraine: Russia

Russia said more of its forces surrounding Ukraine were withdrawing on Wednesday but NATO said the troop buildup was continuing, questioning Moscow’s stated willingness to negotiate a solution to the crisis.   
In Ukraine, the government said a cyber attack that hit the defence ministry was the worst of its kind that the country had seen. It pointed the finger towards Russia, which denied involvement.   
The Russian defence ministry said its forces were pulling back after exercises in the southern and western military districts near Ukraine - part of a huge Russian build-up that was accompanied by demands for sweeping security guarantees from the United States and NATO.   
It published video that it said showed tanks, infantry fighting vehicles and self-propelled artillery units leaving the Crimean peninsula.   
But a senior Western intelligence official said Russian military exercises were at their peak and the risk of Russian aggression against Ukraine would remain high for the rest of February.   
“There are no credible signs at this point that there will be any kind of military de-escalation,” the official said on condition of anonymity, adding that Russia could still attack Ukraine “with essentially no, or little-to-no, warning”.   
NATO Secretary-General Jens Stoltenberg said a pullout would be welcome but that moving troops and tanks back and forth did not amount to proof it was really happening.   
The Kremlin said NATO’s assessment was wrong. Moscow’s ambassador to Ireland said forces in western Russia would be back to their normal positions within three to four weeks.
