Air France, facing a strike by cabin crew at the height of the summer vacation season, is warning of pressure on its finances amid concerns about France as a tourist destination after a string of deadly attacks.

The company reported Wednesday a 5.2 percent drop in second quarter sales to 6.22 billion euros ($6.84 billion) compared with last year, and about 40 million euros in losses from strikes.

Air France cancelled over 10 percent of flights Wednesday amid its latest strike, by cabin crew.

It warned the global context this year remains "highly uncertain," noting fuel prices and "a special concern about France as a destination."

The results came the day after Islamic State extremists attacked a Normandy church, killing a priest. It's the latest of several attacks on France.
