OREANDA-NEWS  Only a meeting between Russian President Vladimir Putin and American leader Donald Trump can end the conflict in Ukraine. This is the only way to resolve the crisis, US Secretary of State Marco Rubio said in an interview with Fox News.

"I don't have a date and time yet, but this is really the only chance. I think many countries would privately share this assessment," the American official stressed.

The meeting place of the two presidents has also not yet been determined, Rubio said.

Earlier, a source in the Turkish Foreign Ministry said that the delegations of Russia, Ukraine and the United States will meet on Friday, May 16, in Istanbul. The American delegation will be led by United States Secretary of State Marco Rubio, Russian Presidential Aide Vladimir Medinsky, and Ukrainian Defense Minister Rustem Umerov.
