Belgian police carrying out a fresh anti-terrorist operation today arrested a suspect, who suffered a slight injury, Schaerbeek Mayor Bernard Clerfayt said.
"I can confirm a police operation targeting a person who was intercepted by police and suffered a slight leg injury," the local official told AFP.
He added there had been several small explosions linked to bomb disposal work.
Police sources said the operation was connected to a foiled terror plot in France.
Amateur video footage on social media shot from an upper storey window shows a man lying by a tram station holding a small backpack.
After being screened by a bomb disposal robot, hooded police grab his legs and drag him away.
A French police source said the raid in the Brussels suburb of Schaerbeek was related to the arrest of 34-year-old Reda Kriket in Paris yesterday, who was found with heavy weapons and explosives in his apartment.
Kriket was sentenced in absentia by a Belgian court in February for his connection to a terror network in Brussels and linked to recruiter Khalid Zerkani.
