Here is what we know so far about the Paris attacks:

The French president, François Hollande, says Islamic State (Isis) is to blame for the coordinated terror attack across Paris that killed at least 129 people on Friday night – the country’s worst terrorist atrocity. He says the attacks were an “act of war … prepared and planned elsewhere, with outside involvement which this investigation will seek to establish”. Hollande adds that France will be “ruthless in its response” and declares three days of national mourning.

Islamic State releases a statement claiming responsibility for the attacks and threatens further attacks against France. The group says the killings were in response to airstrikes against its militants, adding France would remain a “key target”.

The state of emergency declared across France on Friday night remains in place. The measure means most public spaces can be shut down and there is a heightened police and military presence across the country. The French police stress that no public demonstrations are to be held in Paris.

David Cameron chaired an emergency meeting of government ministers and security officials to discuss the British response. A senior Met police officer raised the prospect of increasing the threat level to the UK to its highest possible.

The French government convened an emergency meeting on Saturday morning to formulate its response to the attack. An international investigation was launched overnight and officials have said “accomplices” are still at large.

The death toll at each location was reported as: 87 at the Bataclan theatre; 18 at Boulevard de Charonne; one at Boulevard Voltaire; five at Rue de la Fontaine au Roi; and 14 at Rue Alibert. More deaths were reported on Saturday morning but it is unclear where they occurred. At the Stade de France, the Paris prosecutor, François Molins, says “some” people were killed, possibly three. However, it is not clear whether they are attackers or victims [three suicide bombers and one victime].

Eight [seven] assailants have been killed, seven [six] of them in suicide bombings, a French prosecutor said.

The toll of injured stands at about 200 [352], 99 of whom are seriously wounded.

The first explosion was detonated by a suicide bomber at 9.20pm in the area surrounding the Stade de France stadium north of Paris, where the French football team was playing a friendly with Germany attended by 80,000 spectators. Two other explosions followed at 9.30pm and 9.53pm. President Hollande was at the match and was evacuated from the stadium. One person was killed, along with three suicide bombers.

At the same time, at least three gunmen entered the Bataclan music hall, where a gig by the American band Eagles of the Death Metal was under way. They opened fire at random into the crowd. The attack lasted around two-and-a-half hours and people were held hostage inside. At around midnight French security forces raided the venue. The assault lasted half an hour. The number of dead at Bataclan currently stands at 89. Three of the attackers are killed after activating their suicide vests, the fourth is shot dead by police.

While gunmen were attacking the Bataclan, in Paris’s 10^th district 12 people were killed on the terrace of the restaurant Le Petit Cambodge.

Simultaneously, on rue de Charonne, in the 11^th district, 18 people were killed in gunfire that witnesses say lasted “two, three minutes”.

On Friday night, Hollande ordered the closing of the country’s borders and authorities warned residents to stay inside.

The state of emergency is maintained on all the French territory.

Afternoon summary - what we know

Police have raided a Brussels neighbourhood where three of the attackers are believed to have lived, and made a number of arrests.

One of the attackers at the Bataclan is understood to be a 30-year-old French national, who was known to French police because of links to Islamic radicals.
