Russia on Tuesday demanded NATO scrap its 2008 promise to one day give Ukraine membership of the U.S.-led NATO military alliance and dismissed the idea that NATO member forces could be keepers of the peace under some sort of ceasefire deal.

Russia wants NATO to disavow its 2008 promise to one day give Ukraine membership of the U.S.-led military alliance, and for Ukraine to agree to neutrality, Foreign Ministry spokeswoman Maria Zakharova said on Tuesday.
