"Our navy adhered to international law. We have presented all the evidence. Everybody can see that it was Russian soldiers who attacked our navy. Following this act of aggression, we had to react. That’s why, in some regions, I have declared martial law, because we must protect our country. It is like it was before, in 2014 – Putin wants to annex a further part of Ukraine. He is acting exactly like he did back then," Ukraine's president said.
Poroshenko added that Putin sees himself as a Russian emperor, and his empire cannot work without Ukraine while he regards it as a colony. But, according to the president, Ukraine is no longer a colony since he took his office.
"He (Putin -Ed.) hates the idea that Ukraine wants to become a part of the EU and NATO. That’s the reason behind this renewed Russian aggression. We have indications of a potential offensive on the ground that Putin may be planning. We have presented these satellite images to all of our partners," Poroshenko said.
"Germany is one of our closest allies, and we hope that states within NATO are now willing to deploy naval vessels to the Sea of Azov in order to support Ukraine and to guarantee its safety.
"The only language that he understands is the unity of the Western world. We cannot accept Russia’s aggressive policy. First, it was Crimea, then eastern Ukraine, now he wants the Sea of Azov. Germany also has to wonder: what will Putin do next if we don’t stop him?" the head of state said.
