Fresh Russian military build-up near the border with Ukraine has been reported by NATO.
Anders Fogh Rasmussen, the NATO chief on Thursday said this new development may alarm Kiev and the West.
Rasmussen warned that any Russian intervention across the border could prompt tougher international sanctions.
This comes as Ukraine’s new President announces he would soon implement a unilateral cease-fire to ease the crisis in the restive eastern part of the country.
