In the aftermath of one of the deadliest terror attacks on European soil in over a decade, details are emerging about backgrounds of the men who are suspected of pulling off the attacks.

Paris was wracked by a series of shootings and explosions on Friday night, killing at least 129 people and injuring hundreds more.

ISIS has claimed responsibility for the attack, which French officials say was carried out by three teams of extremists.

One of the attackers has been identified as a 29-year-old French man, who had been flagged for links to Islamic radicalism.

French authorities said Sunday that one man, a probable attacker, is still on the run after the deadly incident.

Here's a look at what we know so far about the attacks:

The latest:

• French security officials said Abdeslam Salah is the subject of a manhunt, and is believed to be one of three brothers involved in the killings. One of his brothers was arrested in Belgium and another died in the attack. Officials told The Associated Press that Salah was questioned by police and freed in the hours after the attacks. Police believe Salah rented a black Volkswagen Polo vehicle that was used by a group of gunmen who killed at least 89 people inside the Bataclan concert hall. French police released a photo of the suspect on Twitter.

• CTV's Genevieve Beauchemin said she was in her hotel near the Place de la Republique when crowds suddenly began to rush out of the square as police officers stormed the area. Police later cleared the iconic plaza, where hundreds had gathered on Sunday for a vigil. Beauchemin tweeted that Parisians cleared the square after hearing noises that sounded like gunfire. Police quickly deemed it to be a false alarm.

• Agence France-Presse reported that authorities in Turkey foiled a major terror plot in Istanbul on the same day as the Paris attacks. The news agency says that Turkish authorities detained five people including a close associate of Mohammed Emwazi, a Kuwaiti-born British ISIS militant also known also "Jihadi John." Authorities are probing to see if the thwarted attack had link to Paris

The attacks:

• In total, the extremists launched six gun and bomb attacks on civilian targets in the French capital on Friday.

• Three suicide bombs targeted spots in and around the Stade de France stadium, in the city's north end, where France and Germany were playing a friendly soccer match. The nearly 80,000 fans, French President Francois Hollande among them, heard the sound of explosion, but the game continued.

• The Wall Street Journal reported that at least one of the attackers had a ticket to the game and attempted to enter the stadium. A security guard told the paper that the attacker who tried to enter the stadium was found to be wearing an explosives vest. The attacker then detonated the vest after attempting to back away from security. Police said he was trying to start a deadly stampede.

• Soon after, a second person blew himself up outside the stadium, and a third suicide bomber detonated explosives at a nearby McDonald's.

• Around the same time, attackers went on a shooting spree at a string of crowded cafes in a trendy Paris neighbourhood.

• The attackers then seized the Bataclan concert hall where the U.S. band Eagles of Death Metal was performing. They opened fire on the panicked audience and more than 100 people were taken hostage. Police later stormed the theatre and three attackers detonated explosive belts, killing themselves.

• Another suicide bomb was detonated on the Boulevard Voltaire, near the concert hall.

Locations of the attacks:

The victims:

• At least 129 people were killed, a majority of whom died in the Bataclan concert hall. Paris prosecutor Francois Molins said at a press conference on Saturday that 89 people died in the attack.

• It is the worst terrorist attack in Europe since 191 people were killed and 1,800 injured during the 2004 bombings of commuter trains in Madrid, Spain.

• There have been few details about the victims of the attacks; however, Canada's Public Safety Minister Ralph Goodale said Saturday evening that there was no information on any Canadians being killed.

• American Nohemi Gonzalez, 23, has been identified as one of the victims. A junior at California State University, Long Beach, Gonzalez was attending Strate College of Design as part of a semester abroad program. Gonzalez was fatally shot in the Petit Cambodge restaurant with a fellow student.

• Djamila Houd, 41, of Paris, who worked for Isabel Marant, a French fashion company, was reportedly killed at a café.

• Five other French men were killed at the Bataclan: Thomas Ayad, 32, a producer-manager for Mercury Music Group; Mathieu Hoche, 38, a technician at France24 news channel; Guillaume Decherf, 43, a music journalist for the French culture magazine Les Inrocks; Fabrice Dubois, who worked for the advertising agency Publicis Conseil; and Cedric Mauduit, a director of modernization for the local government in Calvados, France.

• British citizen Nick Alexander was also among the dead at the theatre. He was working at the Bataclan selling merchandise for the Eagles of Death Metal.

• A 28-year-old woman from Venice, Italy has been identified as one of the victims killed at the concert theatre, Italian officials said Sunday. Valeria Solesin was identified at the Paris morgue, Italian consul Andrea Cavallari said. Solesin had been at the concert with her boyfriend and other friends when shots began ringing out. Her mother said Solesin had been living in Paris for six years and had studied at the Sorbonne.

• Spanish media have also reported that Alberta Gonzalez Garrido, 29, died at the concert. Gonzalez Garrido, an engineer, was living in France with his wife. They were reportedly both at the concert but became separated in the chaos of the attack.

• Chilean exile Patricia San Martin Nunez, 61, her daughter, French citizen Elsa Veronique Delplace San Martin, 35, and her 5-year-old grandson were attending the concert at the Bataclan. Only Elsa's son survived.

• Fellow Chilean Luis Felipe Zschoche Valle, 33, was also killed at the Bataclan. He had lived in Paris for eight years with his French wife, who was with him at the concert. He was a musician and member of the rock band Captain Americano.

• Mexican officials said that Michelli Gil Jaimez, from the country's eastern city of Tuxpan, died in the attacks. She had studied at business school in Lyons, France and was living in Paris. She had also recently gotten engaged to her Italian boyfriend.

• Asta Diakite, the cousin of French soccer player Lassana Diarra, also died in the devastating assaults. Diarra, who was on the pitch for the match against Germany at the Stade de France on Friday later tweeted that Diakite was "like a big sister to me."

The suspects:

• French officials say the co-ordinated terrorist assaults in Paris on Friday night were carried out by three teams of extremists. Seven of the attackers died in suicide bombings, a new terror tactic in France. Authorities say that three of them were French citizens.

• An eighth suspect believed to be directly involved in the killings is on the run and the subject of a manhunt.

• Security officials identified him as the Belgian-born, French national Abdeslam Salah, 26, who is believed to be one of three brothers involved in the killings. One of his brothers was arrested in Belgium and another died in the attack. Police believe Salah rented a black Volkswagen Polo vehicle that was used by the gunman involved in the attack on the Bataclan concert hall. French police released a photo of the suspect on Twitter. One police official said the manhunt is believed to be focused on at least one suspect.

• Authorities said one of French citizens involved in the attacks is Ismael Mostefai, a 29-year-old French citizen, who had been flagged for links to Islamic radicalism. Mostefai's family members have been detained and are being questioned by authorities on Sunday. The Paris prosecutor said the attacker was identified by fingerprints found on a finger that was located amid the carnage at the Bataclan concert theatre.

•Ben Bammou, president of a Muslim group in Chartres, France, described Mostefai to The Associated Press as a "timid" man who regularly attended mosque and used to work as a baker.

• The two other French citizens identified by officials were said to part of the attacks on the Stade de France and a restaurant in central Paris respectively. One of the men was 20 and the other was 31.

• A Belgian official said Sunday that seven people have been detained in connection with the attacks. The official, who spoke on condition of anonymity, said one of the attackers lived in the Molenbeek neighbourhood, which has been a centre for religious extremism and fighters looking to travel to Syria.

• A team of French and Belgian investigators has been established to probe the link between Brussels and the Paris attacks. The official said French investigators have already arrived in Belgium to begin working on the case.

• Molins said that all of the attackers used Kalashnikov assault rifles and wore identical explosive vests, with the same batteries and detonator.

• French police said Sunday that three Kalashnikovs had been found inside a Seat car that was used in the attacks. At this point, two cars are known to be involved in the attacks: a Volkswagen Polo and the Seat. The Seat appears to be linked to the violence that erupted at the Paris restaurants and bars.

• French officials said a Syrian passport was found around the body of one of the suicide bombers near the Stade de France. It is not yet clear if the Syrian passport is fake or real, or if it belonged to the suicide bomber. The passport was linked to a man who entered the European Union from the Turkish coast through the Greek island of Leros last month. The island is where thousands of people fleeing war have been entering the European Union. Greek officials said Sunday that the man stayed there for five days before arriving by ship in Athens on Oct. 8.

• The passport was also registered in October in Serbia and Croatia. Police from the Balkan states said Sunday that the man was allowed to proceed because he passed what is essentially the one test – there were no international warrants out for his arrest.

• UN Secretary General Ban Ki-moon said the response to the attacks should be robust, but must remain within the “rule of law.”

• The New York Times reported Saturday that police in Germany were probing whether a man arrested last week with weapons in his car and his GPS navigator charted for Paris could be connected to the attacks.

What are the possible motives?

• In a statement circulated online, ISIS has claimed responsibly for the attack. However, its authenticity has yet to be verified.

• Hollande said that France would increase its military efforts to crush the extremist group in response. While U.S. President Barack Obama issued a statement saying that it had "no information to contradict the initial French assessment of (ISIS') responsibility."

• ISIS' statement says that it targeted Paris because it is the "capital of prostitution and vice" and condemned the country's airstrikes in Syria, which began less than two months ago.

• The attacks in Paris come less than a week after the French air force attacked an oil distribution centre in Syria controlled by ISIS.

• France joined the U.S.-led coalition in Syria last year and expanded its campaign to include Syria in late September.

• Hollande also announced earlier this month that France was set to deploy an aircraft carrier to the Persian Gulf. The vessel will boost the coalition's airpower. The country already has 12 fighter jets stationed in the United Arab Emirates and Jordan.

What is Paris like:

• The French capital remains somewhat quiet, as the nation remains under a state of emergency.

• Many of the city's top tourist attractions and events throughout the city have been shut down for a second day.

• France's state of emergency will last for 12 days, and parliament can vote to extend it, if need be.

• The majority of flights to and from Paris have not been affected, but stricter security checks have been put into place at all airports, train stations and ferry terminals.

• Schools and universities will reopen Monday with "exceptional" security measures in place.

• All public demonstrations – a constitutional right in France – have also been banned until Thursday.

• Local governments also have the option to impose nightly curfews.

• France is set to go ahead with plans to host the Paris Climate Change Conference Nov. 30.
