One of the attackers at the Bataclan is understood to be a30-year-old French national, who was known to French police because of links to Islamic radicals.
The Guardian’s Ireland correspondent Henry McDonald reports on the comments from U2 frontman Bono on the attacks.
U2 lead singer Bono has said the Paris massacres, especially the attack on the music concert, was Islamic State’s first “direct hit against music”.
Bono said the bombs and bullets at the Eagles of Death Metal concert showed the attackers don’t like music.
“Our first thoughts at this point are with the Eagles of Death Metal fans,” Bono told the Dave Fanning Show on Irish radio 2FM on Saturday.
The U2 star added: “When you think about it, the majority of victims from last night’s attacks were music fans.
“So this really is the first direct hit on music we’ve had on this so-called war on terror.
“We know that they don’t like music … and this and the cold-blooded aspect of last night’s attacks are what are really upsetting because it means it could have been any of us.
Meanwhile Ulster’s European Rugby Champions Cup clash with French side Oyonnax was cancelled on Saturday due to the killings in Paris.
Ulster’s manager Bryn Cunningham said he fully backed the European Professional Club Rugby’s decision to cancel Saturday’s game.
“We fully support the EPRC in this decision – a difficult one and that’s why it took a number of hours on Saturday morning to make it.
“However, rugby is fairly insignificant in all of this. Our thoughts, prayers and sympathies go out to the French public.”
Le Monde reports that a police raid in the Belgian town of Molenbeek is focused on the home of three young men who took part in Friday night’s attack in Paris.
The newspaper says that it involves a second team that fled the French capital on Friday night in a car.
According to witnesses, one of the cars used by the terrorists had a Belgian number plate.

European Union heads of state and institutions have issued a joint statement announcing a day of mourning across Europe on Monday, including a one minute silence.
It is an attack against us all. We will face this threat together with all necessary means and ruthless determination.
Everything that can be done at European level to make France safe will be done.
We will do what is necessary to defeat extremism, terrorism and hatred.
France is a great and strong nation. Its values of liberty, equality and fraternity inspired and inspire the European Union.
This shameful act of terrorism will only achieve the opposite of its purpose, which was to divide, frighten, and sow hatred.
Good is stronger than evil. Everything that can be done at European level to make France safe will be done.
Syrian passport found on Paris attacker's body belonged to refugee who passed through Greece
The holder of a Syrian passport found near the body of one of the gunmen who died in Friday night’s attacks in Paris passed though Greece in October, a Greek minister told Reuters.
“The holder of the passport passed through the island of Leros on 3 October 2015, where he was identified according to EU rules,” said Nikos Toscas, Greece’s deputy minister in charge of policing.
A Greek police source told Reuters that European countries had been asked to check the passport holder to see if they had been registered.
While this heavily implies that one of the gunman came into Europe along with refugees, Syrian passports are known to be valuable currency amongst those trying to enter Europe, and it is not yet confirmed whether the holder of the passport is indeed the perpetrator.
Three Paris attackers 'from Brussels neighbourhood'
Three of the eight attackers who killed 127 people in Paris on Friday night are believed to have come from the Brussels neighbourhood raided by police this afternoon.
French media reports that three attackers were from the Molenbeek neighbourhood, where police are currently carrying out raids.
Reuters reports that one of the gunmen who died after attacking the Bataclan theatre last night was a Frenchman from Courcouronnes suburb south of Paris.
Courcouronnes lies roughly 20 miles south of the French capital and five miles south of Juvisy-sur-Orge, home to Amedy Coulibaly, who was involved in the Charlie Hebdo shootings in January.
Coulibaly killed four hostages in a kosher supermarket in the Porte de Vincennes before being shot by anti-terrorism forces.
A simple sketch combining two of the world’s most familiar images – Paris’s Eiffel Tower and the international peace symbol – has been adopted as a sign of solidarity with victims of the terror attacks in Paris.

The image has been scrawled on T-shirts, painted on banners and chalked onto the streets of Paris, with photographs posted on social media under the slogan Peace for Paris.
The image is said to have been designed by London-based French graphic artist, Jean Jullien. The artwork has gone viral on Twitter, Facebook and Instagram.
A 41-year-old man from France is being questioned by police after “what appears to be a firearm” was discovered at Gatwick airport, Sussex police said.
Downing Street said it believes a small number of British nationals have been caught up in the Paris attacks.
“Our embassy in Paris is working urgently with the French authorities to find out more and we have deployed additional consular staff and a team from the Metropolitan police to assist them with this task,” a spokeswoman said.
Around 400 people called the Foreign Office with concerns about British citizens in Paris, and most have now been located.
The union flag has been lowered to half-mast over Downing Street with the French tricolore alongside as a “clear demonstration of our solidarity with the French”, No 10 said.

The French interior minister, Bernard Cazeneuve, has just finished speaking to the press after a meeting of the Council of Ministers, and announced 1,500 soldiers will conduct patrols in the heart of the capital.
He called for the public prosecutor to be transparent about the progress of the investigation, and said France was working closely “with other European countries to establish the identities of those responsible for these barbaric acts”.
A one-minute silence will be observed in schools and public institutions on Monday.
