PARIS: France made an unprecedented demand on Tuesday for its European Union allies to support its military action against Daesh as it launched new airstrikes on the militants’ Syrian stronghold, days after attacks in Paris linked to the group killed at least 129 people.

France invoked a never-before-used article of the EU’s Lisbon Treaty obliging members of the 28-nation bloc to give “aid and assistance by all the means in their power” to a member country that is “the victim of armed aggression on its territory.”

French Defense Minister Jean-Yves Le Drian said EU partners could help “either by taking part in France’s operations in Syria or Iraq, or by easing the load or providing support for France in other operations.”

Arriving for talks in Brussels on Tuesday with his EU counterparts, Greek Defense Minister Panagiotis Kammenos told reporters that, “we’re in a new situation in Europe. This is Sept. 11 for Europe.”

French military spokesman Col. Gilles Jaron said the latest airstrikes in the Daesh’s de-facto capital of Raqqa destroyed a command post and training camp. On Monday, President Francois Hollande vowed to forge a united coalition capable of defeating the jihadists at home and abroad.

Hollande has said the victims came from at least 19 nations, and the international community, led by the US and Russia, must overcome their deep-seated divisions over Syria to destroy IS on its home turf.

Authorities have yet to announce the capture of anyone suspected of direct involvement in the slaughter, though police have used emergency powers to conduct almost 300 searches since Sunday night that netted 127 arrests and 31 weapons.

A car with Belgian license plates and a shattered front passenger window found Tuesday in northern Paris could be linked to the attacks, officials said. It was the third vehicle identified as having possible links to the investigation.

Meanwhile, the voice of a jihadist claiming Daesh’s responsibility for last week’s attacks in Paris has been identified as a 36 year-old Frenchmen authorities believe is now in Syria, a source close to the investigation said on Tuesday.

The man, Fabien Clain from Toulouse, reads out a pre-written statement already published earlier this week claiming the attacks that killed 129 people and injured more than 350.

Half of the six-minute audio includes a man giving a rallying cry with music in the background calling for Muslims to “move forward” to fight the infidels “without ever capitulating,” according to the audio sent to Reuters.

Police in the western German city of Aachen arrested five people, at least three of them foreign citizens, on Tuesday in an operation linked to the militant attacks last Friday in Paris that killed 129 people.

A special police response unit overpowered two women and one man outside a job center in Alsdorf, a small town near Aachen close to Germany’s border with Belgium and the Netherlands.

A spokesman said the three were foreign citizens but declined to elaborate on their identity pending investigations.

Later on Tuesday, police arrested two more people in Alsdorf, the statement said, giving no details.

European search efforts are focusing on Belgian-born Frenchman Salah Abdeslam, 23, who investigators say escaped back to Belgium on Saturday after the attacks. Austria’s interior ministry said earlier he had entered the country from Germany in early September, telling authorities he was on holiday. .

France and Russia both staged air strikes on Daesh targets in northern Syria on Tuesday as Paris formally requested European Union assistance in its fight against the group behind the carnage in Paris.

Prime Minister David Cameron’s office says he will join Prince William at the friendly soccer match between England and France in a show of solidarity with France after Friday’s attacks.

In Belgium, a lawyer for one of the two people arrested there said his client admits going to France, but only to pick up a friend. Defense lawyer Xavier Carrette told the AP that his client, 27-year-old Mohammed Amri, was arrested over the weekend and is being held on charges of terrorist acts and being part of a terrorist conspiracy.

Kerry flew to France as a gesture of solidarity and met Hollande and Foreign Minister Laurent Fabius on Tuesday.

Standing with Hollande at the Elysee Palace, Kerry said the carnage in the French capital on Friday, along with recent attacks in Egypt, Lebanon and Turkey, made it clear that more pressure must be brought to bear on the Islamic extremists.

Kerry said, “we have to step up our efforts to hit them at the core where they’re planning these things and also obviously to do more on borders in terms the movement of people.”

Hollande said the “acts of war” were decided and planned in Syria, which he said was “the biggest factory of terrorism the world has ever known and the international community is still too divided and too incoherent.”

The attacks “were organized in Belgium and perpetrated on our soil with French complicity with one specific goal: to sow fear and to divide us,” Hollande told Parliament in a rare joint session convened at the Palace of Versailles.

A French security official said anti-terror intelligence officials had identified Abdelhamid Abaaoud, a Belgian of Moroccan descent, as chief architect of the attacks on a rock concert, a soccer game and popular nightspots in one of Paris’ trendiest districts.

The official cited chatter from Daesh figures that Abaaoud had recommended a concert as an ideal target for inflicting maximum casualties, as well as electronic communications between Abaaoud and one of the Paris attackers who blew himself up.

The official spoke on condition of anonymity to discuss the sensitive investigation.
