THE UKRAINE president claims Russia has moved tanks to its borders amid escalating tensions in the East.
It comes days after leader Petro Poroshenko claimed Putin was readying a GROUND INVASION.
Tonight he told reporters: "This is the tank base just 18km from our border, this was happening in September, October, and now.
"This is 18km from my border, this is the same warehouse where they have their ammunition, the same where they have multi-rocket launch system, we should be prepared to protect my country.
"If the whole world has no reason to trust Putin, Ukraine definitely doesn't have a reason to go with him."
He made the shocking allegations in a live TV address to the nation after revealing he is introducing martial law for a month in order to "ensure security."
However, some critics say Poroshenko could be using World War 3 fears as a vote winner ahead of his country's elections.
Earlier Donald Trump dramatically scrapped his G20 meeting with Putin to punish the Russian leader for refusing to release seized Ukrainian sailors.
Tweeting while on his way to the G20 summit, Trump called off the much-heralded crisis talks amid the increasing tensions on the troubled Crimean peninsula.
He wrote: "Based on the fact that the ships and sailors have not been returned to Ukraine from Russia, I have decided it would be best for all parties concerned to cancel my previously scheduled meeting in Argentina with President Vladimir Putin.
"I look forward to a meaningful Summit again as soon as this situation is resolved."
The shock news comes just hours after a Russian official said the two leaders would meet to discuss ways to break diplomatic deadlocks over Syria, Iran and North Korea.
However, the Kremlin insider did not mention Russia's latest clash with the Ukraine which has put the Crimea on a war footing.
