LIVE BLOG: Paris Charlie Hebdo chase

French police have now begun storming the beseiged kosher supermarket.

Four explosions have been heard at the site.

Police have begun storming the industrial park where two brothers suspected of carrying out the Charlie Hebdo massacre had been holed up.

Shots have been heard to ring out, and smoke has been seen rising from the site, near the international Charles de Gaulle Airport.

Explosions have also been heard, reports Reuters. It is known that the two men are holding at least one person hostage.

Chris Morris, reporting for the BBC from a few hundred metres from the warehouse where the brothers are believed to be hiding, says intense gunfire and grenade explosions were heard for about a minute. Things on the ground are quiet again for now, Morris reports.

There are no reports yet of any action at the kosher market, where a gunman is holding at least five people hostage.

The gunman had demanded the release of the two brothers suspected of carrying out the Charlie Hebdo massacre.

Huge numbers of police have been deployed around Rue des Rosiers, a neighbourhood in Paris's 4th arrondissement known for its large Jewish population.

Today it emerged that Friday prayers will not be held in Paris's main synagogue for the first time since World War 2.

Members of the press have been evacuated from the area around the current standoff around a kosher market in Porte de Vincennes, eastern Paris.

Many suspect that a police could move soon to break the standoff, which has seen at least five hostages held for hours.

It has not been confirmed whether there are links between the market standoff and the massacre at the offices of Charlie Hebdo on Wednesday.

However, a police source has told the BBC that the gunman holding hostages at the kosher market has demanded that the two brothers suspected of Wednesday's massacre be released.

The brothers are currently holed up in an industrial park in north Paris, where they are holding at least one suspect.

Many are reporting that the road looks like the home of the "walking dead" after today's shutdown.

Other areas of the city are completely blocked with traffic diverted from the Peripherique, local media reported.

In what French news site TFI News described as a day of "extreme tension" in Paris, the central Trocadero metro station opposite the iconic Eiffel Tower was also evacuated after a false alarm over a possible third attack.

Muslim worshippers undertook Friday prayers in the eastern city of Saint-Etienne next to a banner reading "Je Suis Charlie," the slogan that has united much of the condemnation for Wednesday's attacks.

The rest of the banner reads "They want to snuff out the stars. We want to rekindle them!"

Earlier, hundreds of Muslims in the eastern city of Strasbourg held a minute's silence outside the Grand Mosque.

Israel is "concerned" over the wave of attacks in France over the past few days, according to a statement by Israeli Foreign Minister Avigdor Liebermann. 

Earlier, Israeli Prime Minister Benjamin Netanyahu ordered his country's Ministry of Foreign Affairs and Mossad, Israel's main intelligence agency, to offer "all assistance needed" in fighting the recent attacks in Paris.

The man holding hostages in a kosher grocery on Friday knew at least one of the suspects in the Charlie Hebdo massacre, a source told AFP.

Amedy Coulibaly, 32, was seen with Charlie Hebdo suspect Cherif Kouachi in 2010 during an investigation into an attempted prison break in France. Coulibaly was convicted for his role and was well-known to anti-terrorist police. 

French police have released mugshots of two suspects linked to Thursday's shooting that left one policewoman dead. The two suspects are believed to be involved in the hostage situation at the Paris-area kosher grocery.

According to French newspaper Le Monde, sources have affirmed that Hayat Boumeddiene, whose name appears for the first time, is the ex-girlfriend of Amedy Coulibaly.

They lived together in 2010 at the time of the arrest of Coulibaly. Boumeddiene was with him when he visited the extremist Djamel Beghal in Murat,  in the Cantal region of central France.

French intelligence agents had photographed Cherif Kouachi - one of the suspects connected to the Charlie Hebdo shooting - playing football with Beghal in Murat, where he was on house arrest in 2010, reported the Telegraph. 

Beghal served a 10-year sentence for plotting to blow up the US embassy in Paris in 2001. He has been seen as one of Cherif's mentors. 

These reports show possible links between the Wednesday Charlie Hebdo attackers, Thursday's incident killing a policewoman and Friday's shooting at a kosher supermarket. 

Hassan Nasrallah, secretary-general of Lebanese Shiite militant group Hezbollah, condemned the killings in Paris in a speech on Lebanese TV stating that the actions of "takfiri terrorists" was "more insulting to Prophet Mohammed than cartoons or films mocking him."

At least two have been killed in the hostage drama east of Paris, a source told AFP. 

The hostage situation unfolded after a shooting at a kosher supermarket. Several people have reportedly been injured.

French police say the gunman may be the same suspect behind the killing of a French policewoman in Paris on Thursday. 

For a live news stream following the police operation: 

Brothers suspected in the Charlie Hebdo newspaper attack were cornered with a hostage inside a printing house in small town of Dammartin-en-Goelenear, near Paris' main airport.

Police followed them to the village after suspects Said and Cherif Kouachi and had hijacked a car. 

France's anti-terrorism prosecutor says the shooting and hostage-taking attack is underway at a kosher market on the eastern edge of Paris.

A police official said there are multiple hostages and wounded at the scene.
