Australian Prime Minister Anthony Albanese said Tuesday it was unacceptable for Australian defense personnel to be put at risk in international airspace by the Chinese military as they took part in an operation to enforce United Nations sanctions on North Korea.

A Chinese fighter jet endangered an Australian military helicopter during an unsafe and unacceptable confrontation over the Yellow Sea, Australia said Monday.

The Chinese Air Force J-10 jet dropped flares above and several hundred meters ahead of an Australian MH60R Seahawk helicopter on a routine flight on Saturday in the Yellow Sea as part of an operation to enforce sanctions against North Korea, Defense Minister Richard Marles said on Monday evening.
