The state broadcaster ERT reported that the aircraft was near the town of Karystos on the island of Evia when the crash happened. The aircraft was among at least three other planes along with just over 100 firefighters tackling the wildfires on Evia.
TV reports have shown the Canadair aircraft flying low to drop water on a blazing hillside and as it was pulling up one of its wing tips seemed to strike a tree before control was lost and the aircraft plunged into the ground and burst into flames.
Defence Minister Nikos Dendias confirmed the two pilots had died "in the line of duty... while attempting to protect the lives and property of citizens, as well as the environment of our country".
