The terror attacks in Paris were planned and organised from Syria, according to French Prime Minister Manuel Valls. He also said that intelligence services had prevented attacks from happening since this summer, and know that more attacks were being planned in France and other European countries. The attacks were claimed by the Islamic State (Isis).

Senior Iraqi intelligence officials had warned members of the US-led coalition fighting IS of imminent assaults by the jihadist group just one day before the attacks. The dispatch stated that the group's leader, Abu Bakr al-Baghdadi, had ordered an attack on coalition countries fighting against them in Iraq and Syria, as well as on Iran and Russia.

The dispatch said the Iraqis had no specific details on when or where the attack would take place, and a senior French security official told the AP that French intelligence receives this kind of communication "all the time" and "every day."

A total of 150 raids on suspected Islamist militants have been carried out across France, Valls said. Most of the raids were conducted against radical jihadist not linked to the Friday's attacks but accused of "pouring hatred on the Republic".

The anti-terrorism units Raid and GIPN, both tactical units of French federal forces, were leading the crackdown after the Paris attacks. Local reports suggest several homes in Toulouse, Grenoble and Calais were searched as part of the coordinated raids, alongside operations in a Paris suburb. At least three people have been taken into custody. Some reports suggest several arrests were made.

A total of 129 people died in the attacks on bars and restaurants, a concert hall and the Stade de France. Seven attackers were killed during the attacks, six having killed themselves with suicide explosive belts, and one being shot by a police officer in the Bataclan theatre.
