French plane grounded in Amsterdam after a tweet threatened the flight

A France-bound airliner was grounded for checks on Saturday afternoon at Amsterdam's Schiphol airport after a threatening tweet was received concerning the flight, Dutch border police said.

A police spokesman said that authorities had been searching the flight, operated by Franco-Dutch airline Air France KLM and which had been due to depart around 1345 GMT, for around an hour.

Earlier on Saturday, Dutch Prime Minister Mark Rutte announced heightened security measures for all traffic going from or to France after a horrific night in Paris on Friday where 127 were killed and 180 injured in a coordinated attack on multiple public spaces throughout the city in what French President Francois Hollande has dubbed "an act of war."

ISIS has since claimed responsibilty for the attacks, as well as the bombing of the the Russian Metrojet flight that went down in Egypt's Sinai province earlier this month.
