Ukrainian President Volodymyr and US President Donald Trump spoke on the sidelines of the UN meeting on Tuesday (Wednesday AEST). In the Estonian incident, he said, there was no immediate threat and it was not necessary to fire on the Russian fighter jets. He added, however, that the flight by the Russian jets over the Baltic Sea near Poland last Friday did not justify this kind of response. Three Russian jets violated Estonian airspace for 12 minutes last Friday, before being intercepted and escorted out of the territory by Italian aircraft. On the same day, two Russian fighter jets flew through the safety zone of the Petrobaltic drilling platform in the Baltic Sea near Poland.
