Bodies litter the streets of a Paris alley after a series of coordinated terror attacks in the French capital on Friday, November 13th, 2015
Eerily reminiscent of the simultaneous military and first responder drills taking place during the 9/11 attacks and the London 7/7 bombings, it has emerged that a "multi-site attack exercise" was being carried out in Paris on the same day as the multiple coordinated terror attacks.

Patrick Pelloux, a physician and chairman of a French trade union for EMT personnel, reported in an interview with Radio France the day after the attacks that "as luck would have it, a multi-site attack exercise had been planned [for the morning of Friday 13th], so [Paris EMT personnel] were prepared."

Translated transcript:
"As luck would have it, in the morning at the Paris SAMU (EMT), a multi-site attack exercise had been planned. So we were prepared. What needs to be known is there was a mobilisation of police forces, firemen, EMTs, associations who came [to participate] and we tried to save as many people as possible."
Original French transcript:
"Le hasard a fait, pour vous dire, c'est que le matin au SAMU de Paris, avait été organisé un exercice sur des attentats multisites. Donc on était préparés. Donc ce qu'il faut voir c'est que vous aviez une mobilisation des forces de police, des pompiers, des SAMU, des associatifs qui sont venus et on a essayé de sauver le plus de monde possible."
Who is Patrick Pelloux?

Patrick Pelloux is embraced by the French president at the head of the Charlie Hebdo demonstration in Paris in January this year
From a biography of him of Wikipedia, we read that:

Patrick Pelloux became known in France when was the first to publicly claim that thousands of people were dying in France during the 2003 European heat-wave, which the French authorities denied.

Since 2004, Pelloux has written articles in Charlie Hebdo, the satirical magazine, on the work of an emergency physician.

Since 2008, Pelloux is chairman of 'Association des médecins urgentistes de France' (a French trade union of EMT personnel). He has also been an activist against bullfighting, and has acted in two French movies.

Coincidentally, Pelloux was situated near the magazine's office building during the attack on Charlie Hebdo in January this year. After being called by someone who worked for the magazine - and was presumably inside the building during the attack - Pelloux was one of the first people to arrive on the scene after the shooting. He is said to have immediately telephoned French President François Hollande to tell him what had happened.
