Ukrainian state prosecutors said on Tuesday they had opened a criminal investigation against a Russian law enforcement agency, accusing it of supporting separatist and "terrorist" groups in the east of the country.

Ukrainian President Petro Poroshenko has secured a temporary peace in the troubled east which he says gives him a chance to move Ukraine towards its dream of a place in Europe - but Russia's Vladimir Putin still holds cards that could thwart him.

President Petro Poroshenko proclaimed reforms on Thursday spanning all aspects of life to make strife-torn Ukraine fit for European Union membership, warning his people that without reform they would face a future "alone with Russia."
