Threat that Russia may neglect fulfillment of Minsk Agreements still exists

President of Ukraine Petro Poroshenko has said there is still a threat that Russia can fail to implement Minsk Agreements.

"Is there a threat that Russia fails to fulfill some of the items of the Minsk Agreements? I will be frank with you – it [threat] really exists," the head of state said at a press conference in Kyiv on Thursday.

Speaking on the response, which is to follow if Russia disregards its commitments, Poroshenko said: "Sanctions to be continued, and if the situation is getting worse – sanctions will be toughened."
