Friday’s brutal and barbaric Islamist terror attacks on several locations in central Paris have been described by French President Francois Hollande as “an act of war that was waged by a terrorist army, a jihadist army, by Daesh (Islamic State), against France.”

So far, at least 129 people have died from the attacks, with the death toll likely to rise further, with over 350 injured. According to the Paris prosecutor, Francois Molins, the ISIS assault on Paris was carried out by “three teams of coordinated attackers.” ISIS has already claimed responsibility for the terrorist attacks on social media.

According to media reports, one of the suicide bombers whose body was found outside the Stade de France soccer stadium had a Syrian passport. A Greek official has stated that the Syrian terrorist entered Europe via Greece in October, as a refugee. Another of the terrorists possessed a French passport, and had known links to ISIS.

The Paris attacks are consistent with the kind of mass casualty attacks that have been carried out in the past by Islamist terrorists in London, Madrid, Istanbul, and most recently in Paris itself, with the Charlie Hebdo massacre in January this year. They also came in the wake of last week’s explosion on board a Russian airliner flying from Egypt to St. Petersburg, which U.S. and British authorities believe was a terrorist attack.

 The barbarism and carnage on the streets of Paris are a stark reminder that the free world is at war with brutal terrorist groups who seek to sow death, fear and destruction in the West. This is a moment for robust and bold leadership from leaders on both sides of the Atlantic, who must be prepared to emphatically defeat the enemy we face.
