BRUSSELS // Belgium will keep the highest threat level for Brussels on Monday and will keep the metro as well as schools closed because of a “serious and imminent” threat of coordinated, multiple attacks, the country’s prime minister said.
For the rest of the country, a threat level of three on a four tier scale would remain in place, the Belgian prime minister Charles Michel said.
With the world on edge over the threat, US president Barack Obama said the most powerful tool to fight ISIL was to say “that we’re not afraid”.
In Paris, defence minister Jean-Yves Le Drian said a chemical or biological attack “was among the risks” faced but that all possible precautions had been taken.
Belgian officials met on Sunday evening to review the security alert, imposed over fears militants planned similar attacks to those in Paris which left 130 people dead on November 13.
The city’s metro system and public buildings were closed, along with shops and restaurants after the terror alert was raised to the highest level of four because of what officials said on Saturday was an “imminent threat.”
The historic Grand Place in central Brussels, usually bustling, was virtually empty, with business badly hit in the run-up to Christmas as troops and armed police patrolled.
“A group of 140 called yesterday to cancel a booking. If it continues like this, the Christmas market will be called off with all the impact that could have,” said Patrick, a waiter at one of the many restaurants on the square.
Interior minister Jan Jambon said the authorities were looking not just for Paris suspect Salah Abdeslam who managed to slip past French security forces after the carnage in the City of Light.
“It involves several suspects and that is why we have put in place such exceptional measures,” the Belga news agency cited Jambon as telling Flemish television.
Belgium and the capital, home to the European Union and Nato, are no strangers to violence.
Four people were shot dead at the Brussels Jewish museum last year, and in January security forces killed two suspects linked to the Charlie Hebdo killings in Paris.
The UN Security Council on Friday authorised nations to “take all necessary measures” to fight extremist violence after a wave of attacks, including the downing of a Russian aircraft in Egypt with the loss of 224 lives and the storming of a luxury hotel in Mali which left 19 dead.
Mr Obama said Sunday he would press ahead with a visit to Paris for UN climate talks in December, calling on world leaders to show similar resolve.
“The most powerful tool we have to fight ISIL is to say that we’re not afraid,” he said.
Russian president Vladimir Putin said the Mali attack, in which six Russians died, showed “terrorism knows no borders” and was a global threat which must be confronted “with the broadest international cooperation.”
Moscow announced separately it had killed 11 ISIL-linked fighters in its volatile North Caucasus region.
French president Francois Hollande next week meets world leaders, including Mr Obama and Mr Putin, as well as Germany’s Angela Merkel and Britain’s David Cameron to discuss what can be done to counter the ISIL threat.
Defence minister Le Drian said French jets would be able to launch air strikes on ISIL targets from the Charles de Gaulle aircraft carrier in the eastern Mediterranean starting on Monday.
In Turkey, police arrested a Belgian of Moroccan origin, Ahmet Dahmani, 26, who reportedly scouted targets for the Paris attacks which saw gunmen and suicide bombers hit bars, restaurants, a rock concert and the national football stadium.
The suspected ringleader, Abdelhamid Abaaoud, died in a massive police raid in Paris on Wednesday along with his cousin Hasna Aitboulahcen, reportedly a one-time party girl who turned to radical Islam about six months ago.
Abaaoud was a notorious Belgian militant thought to be fighting in Syria and his presence in Europe has raised troubling questions about a Europe-wide breakdown in intelligence and border security.
Questions remain too over what role Salah Abdeslam — who used to run a bar with his brother Brahim in Brussels — played.
Brahim died when he blew himself up outside a bar in Paris.
A third brother, Mohamed Abdeslam told RTBF television Sunday he believed Salah had changed his mind at the last moment and had not gone through with his attack.
Mohamed Abdeslam said the family wanted Salah to give himself up.
“That way he can give us the answers we seek, our family and the families of the victims,” he said.
“We would rather see Salah in prison than in the cemetery.”
