French authorities say Sunday night‘s airstrikes destroyed a jihadi training camp and a munitions dump in the city of Raqqa, where Iraqi intelligence officials say the attacks on Paris were planned.

Twelve aircraft including 10 fighter jets dropped a total of 20 bombs in the biggest air strikes since France extended its bombing campaign against the extremist group to Syria in September, a Defense Ministry statement said. The jets launched from sites in Jordan and the Persian Gulf, in coordination with U.S. forces.

The Paris prosecutor’s office said one suicide bomber who blew himself up in the Bataclan music hall Friday night was Samy Amimour, a 28-year-old Frenchman charged in a terrorism investigation in 2012. Amimour was placed under judicial supervision, but dropped off authorities‘ radar in 2013 and an international arrest warrant was issued.

An attacker who blew himself up outside the national soccer stadium was found with a Syrian passport with the name Ahmad Al Mohammad, a 25-year-old born in Idlib, the prosecutor‘s office said. It said fingerprints from the attacker match those of someone who passed through Greece in October.

Across France and throughout Europe, people were due to pause for a minute’s silence in memory of the victims of the worst attack on French soil since World War II.

Tension was high in France and Belgium as police looked for a key suspect. The arrest warrant for Salah Abdeslam, a 26-year-old born in Brussels, calls him very dangerous and warns people not to intervene if they see him.

Yet French officials revealed to The Associated Press that police already had him in their grasp early Saturday, when they stopped a car carrying three men near the Belgian border. By then, hours had passed since authorities identified Abdeslam as the renter of a Volkswagen Polo that carried hostage takers to the Paris theater where so many died.

Three French police officials and a top French security official confirmed that officers let Abdeslam go after checking his ID. They spoke on condition of anonymity, lacking authorization to publicly disclose such details.
