A Russian helicopter crashed into the Sea of Okhotsk during joint rescue exercises with Japan, killing one of the 13 people aboard.

The Mi-14 helicopter went down off the Russian island of Sakhalin, north of Japan’s Hokkaido, when one of its rotor blades hit the water during exercises simulating an emergency response to an oil spill and aid to stricken ships.

All 13 people aboard were rescued from the aircraft, but 3 were injured and one of them, a pilot, died on the way to a hospital on shore.

5 crew members and 8 rescuers from Russia’s civil aviation agency had been aboard the helicopter when it went down.

Some of those rescued were taken aboard a Japanese vessel participating in the exercises, and Japanese divers were involved in the rescue operation.

Japanese divers pulled at least one person from the stricken ship.

The exercises involved 7 ships and 4 helicopters from the Russian side and 3 ships and 1 helicopter from the Japanese side.
