France is tightening airport security for U.S. flight destinations for the summer holiday period at the request of U.S. authorities, an official statement said on Friday.
The civil aviation authority warned passengers bound for the United States that they may experience some delays as a result.
Earlier this week the U.S. Department of Homeland Security said it would increase security measures at overseas airports that have direct flights to the United States.
The department did not specify which airports or what countries would be affected, nor did it say what triggered the enhanced measures.
