BRUSSELS (AP) — Belgian prosecutors have charged four more suspects with "participating in terrorist acts" linked to the deadly suicide bombings in Brussels.

The Belgium's Federal Prosecution Office says Saturday that Mohamed Abrini, Osama K., Herve B. M. and Bilal E. M. were all charged with participating in "terrorist murders" and the "activities of a terrorist group" in relation to the March 22 bombings in Brussels' airport and subway. The attacks killed 32 people and wounded 270 others.

The statement says two other suspects arrested in the last few days have been released.
