Protocol V on Explosive Remnants of War requires the clearance of UXO (unexploded ordnance), such as unexploded bomblets from cluster bombs and abandoned explosive weapons. At the cessation of active hostilities, Protocol V establishes a responsibility on parties that have used explosive weapons to assist with the clearance of unexploded ordnance that this use has created. Parties are also required, subject to certain qualifications, to provide information on their use of explosive weapons.
