Brussels: A new blast was heard on Friday from a police operation in a Brussels neighborhood that once housed a hideout for the suicide bombers who targeted the city's airport and subway system this week.
Reporters at the scene described hearing a new detonation, though it was unclear whether it was a controlled police detonation or something else.
Earlier, a witness speaking on Belgian state broadcaster RTBF described hearing two blasts and shots from heavy weapons during the police raid on the Schaerbeek neighborhood.
About 50 officers appear to be involved in the operation. It is unclear whether it is linked to Tuesday's attacks. A tram passing through the area was stopped and evacuated and police cordoned off a wide perimeter of streets.
Belgian state media reported that one person has been detained in police raids in the Brussels neighborhood of Schaerbeek.
Police earlier this week found a large stash of explosives in an apartment in Schaerbeek believed to have been used by suicide bombers in Tuesday's attacks
