The body of a crew member has been recovered from the wreckage of a Canadian military helicopter that crashed in the Mediterranean between Greece and Italy Wednesday evening, according to Greek military officials.

The CH-148 Cyclone helicopter was taking part in a NATO naval exercise when the incident happened at around 9 p.m. local time. It was carrying six crew members, according to the officials.

A search and rescue operation involving standing NATO Maritime Group 2 ships and aircraft, supported by allied maritime and air components from Greece, Italy, Turkey and the United States is underway, according to a NATO statement.

Debris from the craft had been found in international waters in the Ionian Sea, according to the Greek officials.
