Belgian prosecutors say three people detained in the investigation into the attacks that killed 130 victims in Paris in November have been freed after extensive interrogation.

None of the three was charged, the Belgian Federal Prosecutor's Office said Wednesday in a statement.

The three were taken into custody during a police search in the Brussels district of Uccle on Tuesday.

Belgian authorities have not said what they were looking for, or what they may have found.

Brussels was home to many of the attackers who struck the French capital Nov. 13 with suicide bombings and volleys of assault weapons fire. According to Belgian and French investigators, the same cell was behind the suicide bombings that killed 32 victims at Brussels Airport and in the Brussels subway on March 22.
