Delta Air Lines’ page on Facebook was hacked Tuesday afternoon, and the airline said it has removed the “offensive content.”

In response to posts on Twitter about the posts that were showing up on its page on Facebook, Delta tweeted: “The @Delta Facebook page was compromised. We sincerely apologize for the unauthorized, objectionable content that was posted.”

Atlanta-based Delta said it was able to work with Facebook to remove objectionable and offensive content posted to the airline’s page within an hour Tuesday afternoon.

“We are investigating the source of the hack and will incorporate any key lessons to strengthen our social media security measures,” Delta said in a statement, adding that none of its other social media platforms were compromised.
