The Dutch Explosive Ordnance Disposal (EOD) is warning the public about exposed World War II-era munitions, including phosphorous grenades, as record low river levels reveal previously submerged ordnance. The primary concern is the risk of these items igniting and potentially exploding, even if initially appearing inert. Authorities advise anyone encountering such items to avoid contact, immediately contact the police, and move to a safe distance. A recent incident in Doornenburg involved fishermen inadvertently disturbing a phosphorous grenade that began smoking and burning, prompting EOD intervention. While the grenade did not detonate, officials emphasize the potential for a far more dangerous outcome. Much of this wartime munitions was intentionally dumped in rivers after the war, and the porous casings are now vulnerable to accidental ignition with even slight disturbance. Despite the low water levels, reports of exposed ordnance remain relatively limited, but the EOD stresses vigilance.
