Firefighters and emergency workers are attending the scene reported to be near Lake Carcès between Cabasse and Carces, reports Var-matin.
All five passengers on board the two aircrafts have reportedly died following the crash which happened just before 9am local time today.
A local official said both aircraft were from the Army’s School of Light Aviation (EALAT) in the nearby town of Cannet des Maures.
The choppers were believed to be carrying a total of five people, all of them linked to the school although authorities have confirmed they are still searching for other passengers.
"An emergency operation has been launched, with other helicopters looking for possible survivors," said the spokesman, adding it was likely that all died on impact.
EALAT trains helicopter pilots for the French Army, Navy, and Gendarmerie, as well as customs and other civil security agencies.
While the army has reportedly confirmed the incident, the circumstances surrounding the tragedy are still not known.
The helicopters involved were both Aérospatiale Gazelles - a model favoured by the French military.
