A skydiving plane crashed in the eastern town of Tomblaine, killing all 11 people on board, local authorities said on Sunday.
The crash is said to be one of France’s deadliest light aircraft accidents.
The crash killed five instructors, five students, and the pilot, said Yves Seguy, the prefect of the eastern department of Meurthe-et-Moselle.
“There were no bystanders among the victims,” he added.
Seguy said Medical and psychological support teams were caring for relatives of the victims who were present at the airfield, as well as other witnesses.
A source said the students were a group of nurses.
The aircraft, registered in Germany, crashed in a grassy area near the runway of the Nancy-Essey aerodrome, close to a residential area and two roads.
The cause of the incident was not immediately clear.
A technical investigation had been opened, said Amaury Lacote, deputy public prosecutor in the eastern city of Nancy.
Police have advised people on the social media platform X to “strictly avoid” the area around the airport to allow emergency services access.
French Interior Minister Laurent Nunez is expected to visit the scene of the accident in the late afternoon, according to his staff.
