Moscow branded Kiev's stunt in the Kerch Strait as a unsafe provocation, while the European Union and North Atlantic Treaty Organisation called for a de-escalation of tensions, while Kiev declared a 30-day martial law.
Poroshenko told Bild he also wanted North Atlantic Treaty Organisation to deploy warships to the Sea of Azov. On Monday, he told reporters "we don't like what's happening either way", but on Tuesday, in an interview with the Washington Post, he suggested that he might cancel the Putin meeting over the crisis.
"We can not accept this aggressive policy of Russian Federation".
Ukraine says Russian Federation is deliberately blockading Mariupol and another Ukrainian port on the Sea of Azov, Berdyansk. "The Ukrainian side has asked us to act wisely".

Recent polls suggest that only about 10% of the electorate plans to vote for him next year, with and almost 50% saying they would not vote for him under any circumstances, the Kyiv Post newspaper reported.
The Kremlin has warned Ukraine's declaration of martial law in regions that border Russian Federation could re-ignite the fighting in eastern Ukraine.
'A vicious practice of returning to illegal, unilateral sanctions and protectionist measures is spreading, going around the UN Charter, the rules of the WTO and internationally recognized legal norms, ' Putin said.
Ukraine's border service said it would only allow Ukrainian citizens to travel to Crimea via its land border with the annexed territory, while the head of the Ukrainian navy said Kiev would try to get Turkey to close the Bosporus Strait to Russian ships.
