BELGIUM: Belgium Remains On High Terror Alert

Belgian Prime Minister Charles Michel said today that a threat level 4 would remain in effect overnight for Brussels and the Brussels region and level 3 would be maintained for the rest of the country.

"The risk is from an attack similar to the one which took place in Paris, with attacks that could be launched simultaneously in several places", he said.

Possible targets were malls, shopping streets and public transport, Michel said, adding the government would boost police and army presence in the capital beyond already high levels.

Belgian officials on Sunday extended a maximum terror alert for Brussels, prolonging the city's partial lockdown after officials warned of an imminent coordinated attack involving weapons and bombs.

A few of the attackers in Paris are now known to have traveled to and lived in Brussels, sparking concerns about further attacks there.

Belgian prosecutors announce they have detained 16 people in raids linked to possible attacks in Belgium but said Paris fugitive Salah Abdeslam was not among them.

Earlier, Interior Minister Jan Jambon told Belgian TV station VRT: "This is several suspects, which is why we have introduced such a concentration of resources".

"Unfortunately, it's a threat that goes beyond just that individual", he said.

"We have learnt that two terrorists are in Brussels territory and could commit unsafe acts", he said. The capital's metro system also remained shut, and Brussels chief rabbi Albert Gigi said the city's synagogues were closed over the weekend for the first time since World War Two.

The suspected organizer of the attacks, Abdelhamid Abaaoud, a Belgian citizen, was killed during a French police raid Wednesday in the Paris suburb of St. Denis.

Soldiers joined police officers on patrols in Brussels over the weekend.

Brussels was put on the highest threat level, four, on Saturday by its national crisis centre. Local football matches and concerts have also been cancelled.

The Ministry of Foreign Affairs yesterday raised the travel alert for Belgium to yellow, meaning that tourists should pay particular attention to their safety and evaluate if a trip to the country is necessary.

Belgium's Regional Security Council met on Sunday to discuss the measures.

Belgium officials are working with French authorities to track down all those involved in the deadly Paris attacks on November 13.

Authorities say Michel's warning was based on "quite precise information", including the possibility that Abdeslam could be planning a suicide attack in the city.
