Mr Poroshenko said: "There is no red line for Putin and this is the very strong reason why we should be together, the whole civilised world.

"Not only the leaders, with whom [we have] a very reliable partnership, but the people of UK, of Europe, USA, Canada, Australia, Japan, the whole civilised world would be together and this is very important for global security."

His comments come amid rising tensions between the two former Soviet neighbours.

Russia seized three Ukrainian navy ships and their crew in the Kerch Strait after accusing them of venturing into their territory.

Russia is continuing to block the strait and refuses to free the Ukrainian sailors.

Mr Poroshenko referred to the captured sailors as "prisoners of war" and called on Mr Putin to release them, asking for pressure from the international community to encourage this.

Ukraine rejects the charge that they were trespassing in Russian waters and said that two of its ports in the Azov Sea are effectively under blockade by Russia.

Mr Poroshenko said Russia is "strangling" Ukraine with ongoing restrictions.

He said: "They want to hit Ukraine because through Azov Sea, and our sea ports, we export about 40% of our industrial production.

"This is another step for a Russian organised embargo, only buying Ukrainian goods, switching off the natural gas, this is part of the hybrid war that Russia want to attack us."

Moscow denies restricting any shipping.

Martial law has been imposed in some parts of Ukraine over the crisis.

Donald Trump cancelled his meeting with Mr Putin at the G20 amid the ongoing situation with Ukraine. However the Kremlin responded by saying it would mean Mr Putin would have more time for "useful meetings".
