Several Belgian media outlets are carrying reports that Salah Abdeslam, the suspected Paris gunman on the run from police, was spotted by police in Liege on Sunday but escaped in a black BMW.
The reports said Abdeslam headed in the direction of Germany on the E40 motorway and managed to avoid a police checkpoint.
Belgian authorities have not confirmed the reports, saying only that the fugitive was not among those arrested on Sunday and remains at large.
But if Abdeslam did escape police in Liege, it will be the second time he has slipped the net. He and two others were stopped at a French roadblock on the morning after the attacks, near the Belgian border, but were allowed to proceed by officers unaware of Abdeslam's alleged involvement in the attacks.

Belgian prosecutor Eric Van Der Sypt thanked social media users for heeding a police request not to share information about ongoing anti-terror operations, to avoid tipping off suspects.

Speaking at a press conference earlier, Mr Van Der Sypt said police "want to thank the press and social media users because they took the need of this operation into account".
Buzzfeed has compiled some of the best of the cat tweets here.

Freelance cycling journalist Paul Maunder has been at the World Cup cyclo-cross race in West Flanders, Belgium, which has gone ahead with an increased security presence. He writes:
"This winter branch of cycle racing is hugely popular in Belgium. Crowds of up to 40,000 pay to see their idols race through mud, sand and snow. The course here runs through a military base which also uses its barracks to house Syrian refugees.
"Before the race there were rumours that the American team were not being allowed to ride by their embassy. But the Americans are all here, the lager is flowing and the Belgian crowd is as enthusiastic as ever. Their hero Sven Nys has just won, so there is a great deal of singing to his honour as they leave the venue past the row of armed policemen."Copyright: Paul MaunderCopyright: Paul Maunder

The Guardian's Jason Burke - author of several books on Islamic militancy - says recent attacks have succeeded in creating a climate of fear.
The current cycle of militancy "could last for decades", he writes, but the balance of power will shift between the jihadists and the authorities.Quote Message: At the moment there is a tactical stalemate in Syria and Iraq. Isis is able to endure, if not expand.Quote Message: The gap that has opened up between the threat posed by Western Isis volunteers and the resources devoted to countering the threat they pose has made Western nations vulnerable.Quote Message: All this is likely to change in coming years and we can be reasonably confident that the balance of power will swing away again from the extremists, as in previous cycles.
You can see a clip of the interview with Salah Abdeslam's brother Mohamed here, as he appeals for him to hand himself in.
If Salah Abdeslam really did decide against blowing himself up in Paris then he has become a target for the so-called Islamic State as well as for the European authorities, his brother Mohamed Abdeslam's lawyer Nathalie Gallant has told BFMTV.

The Belgian broadcaster RBTF has been speaking with Mohamed Abdeslam - brother of Salah, now the subject of a manhunt, and Brahim, who blew himself up in the Paris attacks.
Mohamed said there had been a slight change in their behaviour about six months ago, but the family did not see it as a cause for alarm.Quote Message: When your brother begins to pray, it's not automatically a radicalistic change. When your brother tells you he stopped drinking, it's not a radicalistic change… For us, these men just wanted to calm down and to show more respect in their practice of religion.
Mohamed said his brothers had been manipulated rather than radicalised - "that's the reason we didn't notice anything" - and said Salah must have had second thoughts during the attack.Quote Message: It's more than my hope, it's my belief. Salah is a very clever man. I think that, at the very last moment, Salah decided to move back. Maybe he saw or heard something that he didn't expect. And he decided not to see the plan through.
Mohamed - who was living with his brothers before the Paris attacks - was initially taken into custody but later released. He repeated his call for Salah to turn himself in, saying his family and the families of the victims needed answers.

Mohamed Abdeslam, the brother of Salah Abdeslam, has again urged the fugitive to give himself up.
He said that he would rather see his brother in prison than in a cemetery.
He told RTBF television that he believed his brother was still alive.
The attacks on Paris this month were a strike against France’s joie de vivre, The New York Times says, while "the siege of Kenya’s gleaming Westgate mall two years ago was an assault on that country’s rising prosperity, modernity and stability".
Likewise the terrifying attack on the Radisson Blu in Mali’s capital was a strike on that nation’s fragile efforts to restore peace after years of fighting, according to the newspaper.
It asks: "But in all of these places, the same fundamental question applies: How does a democratic society protect itself from a few determined extremists who can upend an entire nation with a single devastating strike?"

The Belgian Federal Prosecutor's officer says a review of the security situation in Brussels - and across the country - is being carried out this afternoon.
An announcement will be made at 17:00 local time on whether or not to continue with the security lock-down for the capital, said the BBC's Europe reporter Gavin Lee.
He said: "The maximum security alert will remain in place in the meantime, as Belgian police and security services hunt for suspects linked to the Paris attacks and those said to be planning a similar atrocity in Belgium.
"A spokesman for the Belgian Federal Prosecutor added that there was no information that explosives had been found during a raid in the city over the weekend, despite reports in the Belgian media, though weapons were found in one raid on a property in the city."
Journalist Bert Ryman, who works for Belgian broadcaster VRT, says the government has some difficult decisions to make.
"It's one thing to close down a city, if you want, for a weekend but it's another very much more bigger problem if you do that for a Monday morning when a lot of people are having to go to work," he said.
"I heard about a lot of companies emailing their staff saying that if the threat level would still be [at the highest level] and if, for instance, the subway station would not be functioning tomorrow morning, people are advised to stay at home, to work from home."

Britain plans to increase the number of fighter jets it can launch from new aircraft carriers as it seeks to boost its military attack capabilities, Chancellor George Osborne tells the BBC's Andrew Marr Show.
"We are going to step up the aircraft carrier punch of the United Kingdom. We are going to make sure that when these aircraft carriers are available they are going to have planes that can fly from them in force," Mr Osborne said.
Asked if he would rule out police cuts, he said: "Every public service has to make sure it is spending its money well."
The chancellor said the counter-terrorism budget was being increased and more money would be spent on defence.
Islamic State (IS) militants have issued a new video which claims that recent French strikes on the group's Syrian stronghold of Raqqa hit civilian buildings without causing any casualties.
The video issued on 22 November was released by IS's so-called "Al-Raqqa Province" in French and Arabic. It showed footage of two buildings that were extensively damaged.
The video claimed that the buildings housed "the Central Administration of Bakeries" and a "medicines warehouse".
The militant in the video also vowed revenge against France for the airstrikes - and that the Paris attacks were "just a warning" aimed at telling the French that "we can reach you anywhere".

UK shadow chancellor John McDonnell says it is unlikely that military action alone would end the threat from Islamic State militants.
He told the BBC's Andrew Marr Show: "This isn't a war like the Second World War, where you fight against an enemy in one terrain, you defeat them, they sign a peace treaty and that's it.
"I think Isil... basically they're encouraging the UK and US to get involved in a war in the Middle East again, because it plays to their narrative of crusader invasion.
"And remember if we did defeat Isil in some form, they have another army and that army we've seen is located in most of our capital cities."
The Syrian city of Raqqa was once a bustling town - but it has now been transformed under the "brutal rule" of Islamic State militants.

Shakespeare & Co. became a hiding place during the terror attacks on Paris.
Like other shops and restaurants in Paris, the shop shuttered its doors with customers inside, until they decided it was safe.
"We are safe in a bookshop, with the windows blacked out," Harriet Alida Lye wrote to The Guardian, during the attacks. "There are about 20 customers with us who've been [sitting] here for hours, calling home.
"I haven't seen anything but police cars go by and people stumbling out of bars in central Paris who clearly have no idea what is going on."
Bookseller Rose Alana Frith told BuzzFeed those hours are unforgettable.
“Surrounded by a medley of familiar and previously unknown faces in the darkened stairwell, as events unfolded, I felt comforted.”

You can read more about the Belgian connection to the Paris attacks here.
The fugitive Salah Abdeslam had a suicide belt on after the Paris attacks, a lawyer for one of the men who drove him to Belgium has told Belgian TV.
Hamza Attou was in the car with Salah Abdeslam and has told his lawyer Carine Couquelet that Abdeslam was extremely agitated during the journey.
Ms Couquelet said her client had told her he appeared to have a large jacket and may have been ready to blow himself up.
She said this raised questions, including whether Salah Abdeslam may have been supposed to blow himself up during the Paris attacks but had second thoughts.
The car carrying him was stopped by police three times on the journey from Paris, she said, but the cursory nature of the identity checks meant officers did not notice anything untoward.
Sir Richard Branson urged people not to judge all Muslims - almost a quarter of the world's population - based on the actions of a few jihadists.
"Social media is abuzz with the angry comments of those who are trying to blame the global Muslim community for the deadly events of Paris. Others have been stoking fears that the wave of refugees trying to escape the horrors of war and oppression in Syria is really just a Trojan horse for the passage of travelling jihadists.
"We wouldn’t blame all Americans for the past actions of the Ku-Klux Klan. But it seems some people have no problem judging every woman riding the tube in a hijab to be a terrorist."

The so-called Islamic State and Saudi Arabia - in its struggle against terrorism, the West wages war on one, but shakes hands with the other, Kamel Daoud writes in the New York Times.
"This is a mechanism of denial, and denial has a price: Preserving the famous strategic alliance with Saudi Arabia at the risk of forgetting that the kingdom also relies on an alliance with a religious clergy that produces, legitimises, spreads, preaches and defends Wahhabism, the ultra-puritanical form of Islam that Daesh (Islamic State) feeds on."

Reuters reports on the story of a nurse who discovered that a man he was trying to save was one of the Paris bombers.
David explained that following what he thought was a gas explosion in the Comptoir Voltaire cafe, he began CPR on a man who appeared to be unconscious.
But when he tore open the man's shirt, he saw wires.
“The first wire I saw was red. I think that was the detonator,” he said. “There was something at the end.”
The man was Brahim Abdeslam, the only person to die at the cafe.
“[Later] I was thinking about how I lay him on the floor, with me doing CPR," said David. "It’s a pretty vigorous process. By just doing that, I also could have been gone."

Professor Fawaz Gerges, professor of international relations at the London School of Economics, told the BBC's Tom Burridge there were "new tactics on the part of the so-called Islamic State".
"We are seeing a major shift on the part of Islamic State, away from Syria and Iraq and, in particular, towards foreign targets and the heart of Europe," he said.
He said European governments needed "iron-clad security in terms of prevention".
But he added that it was important not to "play into the hands" of the militant group.Quote Message: We must not exaggerate the security risk. We must not be in fear of our lives - that is exactly what they are trying to do.Quote Message: If you ask me what is the strategic message of the so-called Islamic State, I would say they want to instil fear. They want to terrorise European and Middle-Eastern societies - whether Beirut or Paris - that's what they want.Quote Message: We must not allow them to do so. We must live our lives normally and find ways and means to prevent radicalisation that has taken place in many societies.
