Update
BRUSSELS — Belgian state media is reporting that two explosions have been heard and one person has been detained in police raids in the Brussels neighborhood of Schaerbeek.
It is not clear whether the raids are linked to the investigation into deadly attacks Tuesday on Brussels’ airport and subway system. At least one suspect in those attacks is at large, and it is unclear whether there were other accomplices.
State broadcaster RTBF says multiple police operations are under way in Schaerbeek, and one person has been detained. It says one explosion was heard at the start of the operation and cited witnesses describing gunfire.
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.
