France coach Didier Deschamps has said FIFA will look into claims one of his side's training sessions was disrupted by a drone flying overhead earlier this week.
The incident is believed to have taken place on Tuesday at France's World Cup training camp in Ribeirao Preto, north of Sao Paulo, as they prepared for their opening match against Honduras in Porto Alegre on Sunday.
"Apparently drones are used more and more," said Deschamps.
"We don't want intrusion into our privacy. It's hard to fight.
"It's not up to me -- FIFA handles this and has been carrying out an inquiry."
FIFA is yet to comment on the matter.
