President Barack Obama called on the European Union Tuesday to implement an agreement that would require airlines to share passenger information.

Obama, at a joint news conference with French President Francois Hollande, said there was growing recognition in Europe after the November 13 attacks in Paris that more needs to be done to prevent the flow of foreign fighters.

"As part of that, I'm calling on the European Union to finally implement the agreement long in the works that would require the airlines to the share passenger information to do more to stop the foreign terrorist fighters from entering our countries undetected," Obama said.
