Travelers at Paris' Charles de Gaulle airport are sharing reports of long waiting times as France's security tightened in the wake of the terrorists attacks in Paris Friday.

"I've been in the queues for over 2 hrs," one person tweeted. "2+ hour wait," tweeted another.

"Strengthening controls. Further delays expected. Thank you for your understanding," says a note on Charles de Gaulle's official site.

Shortly after the string of attacks in Paris late Friday and early Saturday, France's president Francois Hollande reinstated border controls, calling the attacks an "act of war". More than 120 people were killed in the attacks, with dozens more injured, many of whom are in critical condition.
