One person died and four others went missing after two cargo ships collided in an incident that took place in the North Sea off the coast of Germany. An additional two crewmembers were rescued, according to German officials. The British-flagged Verity is said to have collided with the Bahamian-registered Polesie. Reports say the Verity sank. The Polesie remained afloat. The Verity was traveling from Bremen to Immingham in the U.K. when it collided with the Polesie, which had departed from Hamburg on its way to La Coruña in Spain. The incident happened off the coast of Heligoland. Rescue ships from the German Maritime Search and Rescue Service (DGzRS), a German navy helicopter and a water police boat are aiding in the search efforts, the DGzRS said. No word as yet on the cause of the collision.
