Two French soldiers were badly wounded in Iraq and two Peshmerga fighters were killed by a booby trapped drone sent by a group related to the Islamic State, Le Monde reported on Tuesday, October 11, according to The Sydney Morning Herald.

In what could be the first report of an attack by Islamic State militants on French special forces using a drone, the device was intercepted while flying and exploded after landing on the ground, the paper said.

Le Monde said the attack happened on Oct. 2.

It was not clear whether the device was remotely detonated or if it carried a timed bomb.

The two French soldiers were immediately repatriated to receive medical treatment in France. One of them "is between life and death," the newspaper said.

Other French soldiers were also lightly wounded by the explosion but Le Monde did not give precise numbers.

France has about 500 military in Iraq as part of a US-led coalition to fight Islamic State militants. The numbers include special forces that have been training Kurdish Peshmerga forces in the north of the country.

The French defence ministry, which has a policy of not discussing special forces' operations, declined to comment on the Le Monde report.
