After government legislation drafted in by David Cameron, airstrikes have commenced against ISIL targets in Syria.

More than 120 people are believed to have been killed in a series of attacks across the French capital.

This is how the events unfolded at six locations in Paris:

:: Stade de France - Bombings

Blasts were heard near the stadium in the north of Paris around 9.30pm local time on Friday.

Police later confirmed there were three simultaneous bombings, including two suicide attacks, near the stadium as France played Germany in a friendly match.

French President Francois Hollande, who was at the game, left immediately as hundreds of anxious fans spilled on to the pitch.

A prosecutor said people there had been fatalities, but did not confirm the number. A police union official said three people had died.

The blasts occurred near two of the stadium entrances and at a nearby McDonald's restaurant.

:: Restaurant And Bar - Shooting

Around 10:30pm, there were reports of a shooting at a restaurant on Rue Alibert in the 10th arrondissement, about five miles away from the Stade de France.

At least 14 people were later confirmed dead in the rampage at Le Carillon, a bar-cafe, and the nearby Cambodian restaurant Le Petit Cambodge.

Witnesses said gunmen armed with Kalashnikov assault rifles fired at victims through the plate-glass windows.

:: Bataclan Concert Hall - Bombings And Shooting

By 11pm reports emerged that the popular music venue on Boulevard Voltaire in the nearby 11th arrondissement was under attack.

Early reports suggested 15 people had been shot dead in the concert hall, where American band Eagles of Death Metal was due to play.

Dozens of hostages were taken inside the venue.

A short time later, security forces launched an assault on the theatre. The two attackers were killed after detonating explosive belts.

More than 80 concert-goers were killed in the venue. Initial reports suggested 120 people were killed.

Several people inside the venue survived the massacre. The band was also confirmed as safe.

One person was also killed on Boulevard Voltaire, not far from the venue.

:: Cafe - Shooting

Less than a mile from the concert hall, at least 18 diners sitting on outdoor terraces at La Belle Equipe in the popular Charonne area were shot dead.

Emergency workers covered bodies on the pavement outside the traditional Parisian cafe.

Police appeared to be still searching for suspects later.

:: Pizzeria - Shooting

Five people were killed in La Casa Nostra pizzeria on Rue de la Fontaine au Roi in the 11th arrondissement.

Witnesses reported seeing a man firing a machine gun.

:: Attackers Killed

Eight extremists involved in the attacks have been killed, the prosecutor said.

Seven died in suicide bombings, while the other was killed in the concert hall.

No terror group has claimed responsibility.

Some witnesses in the hall said they heard the gunmen shout Islamic chants and slogans condemning France's role in Syria.

During a televised address amid the attacks, the French President, without naming any group, said: "We know where these attacks come from. There are indeed good reasons to be afraid."

Visiting the Bataclan theatre in the early hours of Saturday, Francois Hollande said France will be "merciless" against those who have attacked the country.
