The authorities in Belgium have launched six raids in the Brussels region linked to Bilal Hadfi, AP is reporting.
Hadfi is believed to have detonated a suicide bomb outside the Stade de France in Paris last week.
A 20-year-old French national who lived in Neder-over-Hembeek in Belgium, Hadfi was described as being until recently a "typical teenager who was obsessed with football."
Hadfi started to become radicalized, however, and after the attacks on Charlie Hebdo in January "there was a week of school left during which he told his classmates he was going to Syria," one of his former teachers said.
Reuters has a few more details about the reports that Belgian police have carried out a series of raids today in Brussels linked to last week's attacks in Paris.
One raid was carried out in the Brussels district of Molenbeek and another in the neighboring district of Jette, a police source said, but would not say whether any arrests were made.
A government source would not comment on reports that the raids were linked to Bilal Hadfi, one of the Paris suicide bombers who had been based in Belgium.
A number of French news sites are posting profiles of Hasna Aitboulahcen, the French-Moroccan woman French media has named as the suicide bomber who blew herself up during yesterday's police raid on an apartment block in a northern Paris suburb.
However, L'Express reports that the Paris prosecutor refused to confirm this morning whether Aitboulahcen was the suicide bomber, saying that identification of the suicide bomber's remains is still ongoing.
If Aitboulahcen is formally identified as the woman who blew herself up, she will be the first ever female suicide bomber in France.
According to L'Express, Aitboulahcen was born in August 1989 in Clichy-la-Garenne in the northwest suburbs of Paris. She is reportedly the cousin of the suspected Paris attacks mastermind, Abdelhamid Abaaoud, though this has not been confirmed.
L'Express also noted that a Facebook page presumed to have belonged to Aitboulahcen included photos of the young woman holding weapons. Aitboulahcen's presumed Facebook page reportedly also included messages glorifying Hayat Boumeddiene, the wife of Amedy Coulibaly, the hostage-taker and gunman in the Hypercacher kosher supermarket in Paris in January.
Aitboulahcen had wanted to go to Syria like Boumedienne, according to her Facebook page.
The 26-year-old had also run a construction company, Beko Construction, until December 2013, coincidentally -- as L'Express notes -- the time when Abaaoud is thought to have gone to Syria.
Chilling video footage has emerged showing the instant a gunman attacked a cafe, spraying it with bullets during last week's coordinated attacks that killed 129 people in Paris.
The four-minute video shows terrified people trying to find cover as the gunman shoots through glass windows and doors.
French war planes have destroyed 35 IS targets in Syria during a series of air strikes in response to last week's terror attacks in Paris that killed 129 people, the country's military say.
Around 60 bombs have been dropped at six sites that target IS's training sites and command centers, according to French military spokesman Col. Gilles Jaron.
The aim of the strikes was to weaken IS and its ability to organize, Jaron said.
The activist group Raqqa Is Being Slaughtered Silently (RBSS) tweeted photos yesterday of several IS sites in Raqqa they said were hit by the French strikes. RBSS claimed that the sites included an IS weapons cache, a training base and a security headquarters.
Nearly two-thirds of Britons support putting British troops on the ground to fight IS following the attacks on Paris last week, according to a poll.
A similar number also support air strikes against Syria, according to the poll run by ComRes for the Daily Mail.
Unlike France and the United States, Britain currently only undertakes air strikes against IS in Iraq. A motion by the British government to bomb Syrian President Bashar al-Assad's forces in Syria in August 2013 following deadly chemical weapons attacks was defeated in the British parliament.
Abdelhamid Abaaoud, the suspected mastermind of the attacks that killed 129 in Paris was among those killed in a police raid in a suburb of the French capital on Wednesday, the Paris prosecutor said in a statement on Thursday, Reuters reports.
"Abdel Hamid Abaaoud has just been formally identified, after comparing fingerprints, as having been killed during the (police) raid," the statement said.
"It was the body we had discovered in the building, riddled with bullets."
Abaaoud, 28, was a Belgian militant who bragged about mounting attacks in Europe on behalf of IS.
The prosecutor said that it was unclear at this stage whether Abaaoud blew himself up or not, according to Reuters.
AP, which gives Abaaoud's age as 27, is reporting that Abaaoud was identified "based on skin samples."
The U.S. Embassy in Rome has identified some of Italy's most popular tourist sites as potential targets for terrorist attacks, warning U.S. citizens to "remain vigilant and aware of their surroundings."
St. Peter's Basilica in Vatican City, the Duomo and La Scala in Milan as well as "general venues" like churches, synagogues, restaurants and theaters in both cities were named as "potential targets."
"Terrorist groups may possibly utilize similar methods used in the recent Paris attacks," the embassy website has warned.
French officials have yet to confirm the identity of the woman who blew herself up with an explosive vest at the beginning of yesterday's raid on an apartment block in a northern suburb of Paris.
AP is reporting that three police officials have said the woman was the cousin of Abdelhamid Abaaoud, the alleged mastermind of the Paris attacks, who the Paris prosecutor has confirmed was killed in the raid.
Various French news sites have also reported that the woman was Abaaoud's cousin, but this has not been officially confirmed.
AP say that one official said the woman was believed to have detonated her suicide vest after a brief altercation with police officers.
The official said that one of the officers asked the woman where her boyfriend was. She responded: "He's not my boyfriend," and then there was an explosion.
AP also includes the grisly detail that the bodies recovered from the raided apartment were "badly mangled, with part of the woman's spine landing on a police car."
Euronews reports that Paris's Saint-Denis district, the site of yesterday's dramatic police raid on an apartment block, is slowly returning to normal.
Schools have reopened after being closed on November 18.
But there is still a heavy security presence in the neighborhood and local residents say they are concerned that the current state of emergency will mean more checks and security.
"How many people did they kill? It’s really, really serious. I can’t even speak, I am shocked," one Muslim woman who lives in the area told Euronews.
