Ukraine and Russia conflict started when an Ukrainian boat illegally entered russian waters, as russian sources confirm. Then, two russian army boats decided to seized the ukrainian boat with people getting injured inside.
After this, Russia decided to place a barrier in the Sea of Azov, closing Kerch Strait, only entrance to it, to maritime traffic.
Russia confirmed use of force against ukrainian boat and alleged that nobody informed they were going to navigate in their waters, opposite to Ukraine information that reported to inform the Russians of its plan to move its ships to Mariupol.
As a result of this confrontation between Ukraine and Russia, President of the United States Donald Trump has canceled scheduled meeting with Vladimir Putin until Russia doesn’t return ukrainian ships and sailors.
….in Argentina with President Vladimir Putin. I look forward to a meaningful Summit again as soon as this situation is resolved!
