With France reeling from the series of attacks that struck the heart of the city in Paris with bombings and multiple shooting that have left over 150 dead, many supporters and sympathisers of ISIS took to social media to celebrate the brutal carnage using the hashtag 'parisisburning'.
A tweet said, "God is great and thank God for these lone wolf attacks. At least 100 hostages and countless wounded."
There were messages boasting predictions of similar horrific attacks in Washington DC and London.
An ISIS sympathiser tweeted after the attack saying the attack would be imprinted on the minds of every Parisian they way it has been established in the minds of Americans after 9/11.
However, the extremist terrorist organisation is yet to officially take responsibility for the deadly attacks. Their customary method of doing so usually includes the circulation of a video or an audio recording justifying their attack or execution.
Eyewitnesses reportedly saw gunmen shout out 'it's for Syria' and 'Allahu Akbar' (God is great) before opening fire and slaughtering around 100 people inside the Bataclan concert hall where music fans were attending a concert.
