Passengers aboard an Air France flight faced a scary descent after crew members discovered an item they initially thought could be a threat to the plane.
However, the CEO of Air France said the suspicious item that led a Paris-bound plane to make an emergency landing in Kenya was a "false alarm."
Frédéric Gagey said the item found in the plane's bathroom appeared to be made of "cardboard, papers and what looks like a kitchen timer." The Air France flight, traveling from Mauritius to Paris, made an emergency landing early Sunday in Mombasa, Kenya, after the item was found.
"From the photos provided by the Kenyan authorities, nothing in the object found posed a threat for the plane or passengers," he said.
Bomb experts retrieved the item to examine it, said Kenyan police. The passengers were rerouted to Paris on another flight.

"The sheer amount of cocaine seized in this case is staggering," New York City's Special Narcotics Prosecutor Bridget G. Brennan said. "This is the largest seizure of cocaine being transported in the region that our office has handled in recent years."
