Overview

• Shortly before 06:00 Monday, an explosive detonated at a portiek on Berkelstraat in Rotterdam-Kralingen, scorching the door and melting plastic on the stoop as officers sealed the area for forensic work.
• A 20-year-old Rotterdam man was arrested shortly after the blast, and investigators are probing possible ties to two earlier explosions and a shooting at the same home in May.
• Neighbours reported seeing two boys with hoodies and a shopping bag just before the Rotterdam detonation, and police are appealing for witnesses and camera footage.
• Around 13:00 Sunday, a powerful explosion on the fourth floor of a 12-storey flat on Ocarinalaan in Rijswijk triggered fire and additional blasts that blew out part of the gallery façade.
• The Rijswijk fire was brought under control with no injuries reported; a trauma helicopter landed, a police helicopter circled, damage is being assessed, and displaced residents are being assisted by Stichting Salvage.
