Brussels: Prosecutors on Sunday disclosed a growing Belgian connection to the Paris attacks as Premier Charles Michel conceded that a Brussels neighbourhood is a "gigantic problem" given its past links to international terrorism.
Belgian prosecutors cooperating with their French counterparts said two assailants killed in Friday's attacks were Frenchmen who had lived in Brussels, that two cars tied to the attacks found in Paris were rented in Belgium, and Belgian police have detained seven people.
At least one of the dead assailants and five of the people arrested in raids Saturday had spent time in the poor immigrant Brussels district of Molenbeek, officials said.
Belgium also issued an international warrant for the arrest of Salah Abdeslam, who lived in Molenbeek, while his brother Mohammed, who was arrested in this neighbourhood while returning from Paris, is still in custody, officials said.
A third brother Brahim died after having set off his explosives-laden suicide belt near a cafe in Paris' 11th district, investigators said.
The trail led to the three brothers following the discovery of two cars registered in Belgium, one of them near the Bataclan concert hall where 89 people were gunned down, and the other in a Paris suburb, Belgian prosecutors said.
The results of the probe so far highlight how Molenbeek has for two decades lodged Islamist extremists who have fought or supported wars in Algeria, Afghanistan and Bosnia as well as in Syria and Iraq, analyst Claude Moniquet told AFP.
"It's not the only one in Belgium, it is certainly not the only one in Europe, but it is a hotbed for jihadism," Moniquet said.
Belgium as a whole has spawned nearly 500 jihadists for Syria and Iraq from a population of only 11 million — the highest figure per capita in the European Union, security services said.
What is striking is that Belgium and more specifically Molenbeek remain a haven for extremists despite the toughening of anti-terrorist legislation as well as the dismantling of recruitment networks since the 1990s.
"Europe no longer has borders and it is therefore logical that (extremists) benefit too," Brussels mayor Yvan Mayeur said Sunday.
"But we must stop being a base for those who make war in Europe," he said.
Molenbeek, where a large Muslim community lives, including a radical minority, is more than ever in the eye of the storm.
"Among this small minority, there are figures known at the European and international levels," according to Moniquet, CEO of the Brussels-based European Strategic Intelligence and Security Center.
They lure people online, he added, comparing the neighbourhood's jihadist influence to that of Finsbury Park in London about 15 years ago.
Part of the reason Molenbeek became such a hotbed is because local politicians failed for years to face up to extremism in order to keep "social peace" and continue getting elected, Moniquet said.
Belgium's Premier Michel acknowledged the problem on Sunday.
"I have noticed there is almost always a link to Molenbeek, that there is a gigantic problem there," he said.
"In the last few months, many initiatives have been launched in the fight against radicalisation, but there should be a greater crackdown," Michel added.
"We are going to work more intensely with the local authorities. The federal government is ready to provide more means."
In 2001, it was in Molenbeek where the assassins of Afghanistan's anti-Taliban commander Ahmad Shah Massoud had stayed.
It was also home for a while for Hassan El Haski, who was found guilty of being one of the masterminds of the 2004 Madrid train bombings.
Mehdi Nemmouche, the main suspect in the Jewish Museum attack in Brussels in May last year, also stayed there.
Ayoub El Khazzani, the perpetrator of the foiled attack in August on the Paris-bound train from Amsterdam, stayed in Molenbeek with his sister before boarding the locomotive in Brussels.
Belgian authorities have also established links with the jihadist cell that police smashed in the eastern Belgian city of Verviers in January.
"They do not all come from here, and most of the time, they are just travelling through," according to Molenbeek Mayor Francoise Schepmans, a member of Michel's liberal party MR.
"In some districts, the population is very dense, with 80 percent of the people of north African origin. Anonymity is easier for people passing through with very bad intentions," she said.
"They also land in districts which are breeding grounds for radicalisation," she said, before taking a dig at her socialist predecessor: "One should have been firmer from the start."
