US President is scheduled to meet Putin at the G20 summit in Buenos Aires at the end of this week; however, he said that it would depend on the results of a report about the incident being prepared by his national security advisers.

He is quoted to have said:”Maybe I won’t have the meeting. Maybe I won’t even have the meeting,”

Ukrainian President warned that the clash at sea could herald more drastic developments in the simmering Ukraine-Russia military standoff.

“I don’t want anyone to think this is fun and games. Ukraine is under threat of full-scale war with Russia,” said the president.
