In a separate, more severe incident in the Osdorp district of Amsterdam, an explosion near a gym injured seven people and led to the evacuation of approximately 400 residents. Following the blast, investigators recovered a pistol, a machine gun with 200 rounds of ammunition, and bomb-making materials in a nearby basement. The Dutch Public Prosecution Service indicated that the materials suggest suspects may have been preparing to attack ATMs. Two suspects, Yassin B. and Nawfal T., were detained after sustaining serious injuries during the explosion.
