AKIPRESS.COM - Brussels will stay on the highest level of terror alert because of the "serious and imminent" threat of Paris-style attacks, Belgium's prime minister says.

Charles Michel added that universities, schools and the metro would stay shut.

Brussels has been on lockdown all weekend, amid a manhunt for suspected Paris attacker Salah Abdeslam.

A suicide bomber pictured in a new French police appeal arrived in Greece under the name of M al-Mahmod, BBC said.

The BBC's Ed Thomas has matched the image released by French police with a photo on the arrival papers of a man who reached the Greek island of Leros on 3 October.

The man was with a group of Syrian refugees and with another attacker who was travelling under the name of Ahmad al-Mohammed.

French police have asked for more information about the man, whom they say was the third suicide bomber to strike the Stade de France on 13 November.

Islamic State militants, some of them from Brussels, killed 130 people in Paris on 13 November.

Security forces completed several operations in Brussels on Sunday night, the AFP news agency reports. The police had urged the public not to report its movements on social media.

Earlier on Sunday, the Belgian prime minister told reporters in Brussels that the authorities fear "an attack similar to the one in Paris, with several individuals who could also possibly launch several attacks at the same time in multiple locations".
