Supporters of the evil terror organisation made the chilling threats online after at least 128 people were killed in Paris, France last night.
Today David Cameron will chair a Cobra meeting where top politicans and security officials will be discuss raising Britain’s terror threat to its highest possible level.
If raised to “critical” it would be the first time since June 2007 – after a car loaded with propane canisters was driven into a crowded Glasgow Airport – that the threat to the UK has been so high.
This morning President Hollande confirmed the atrocities in Paris were carried out by ISIS – describing the attacks as an “act of war”.
The news comes as at approximately 10am the north terminal of Gatwick Airport was evacuated with many fearing ISIS had been true to their word and struck in Britain.
