Today, the threat of Russian invasion prevails, the president believes.

“If we had any reason to talk about de-escalation, I would cancel martial law,” Poroshenko told a press conference in Kyiv Sunday, according to an UNIAN correspondent.

Russian troops were this time deployed toward the borders with Ukraine not for some exercises – Russia did this without any explanation, Petro Poroshenko says.

"We have confirmation of this from satellite imagery, we have a clear picture from interceptions on when they [Russian troops] were deployed and for what purpose," the president added.

“Today, there was and still is a threat of invasion of Russian armed forces into the sovereign territory of Ukraine, and we certainly should be prepared for this. We will not let the year of 2014 repeat itself. My goal as president is de-escalation,” Poroshenko stressed.
