Four people were killed after a small plane crashed in western Germany's state of Rhineland-Palatinate on Sunday, police said. A business aircraft came down near Sehlem on the Moselle River on Sunday lunchtime, killing all four people on board, a police spokesman told local media. The twin-engine jet fighter crashed on a landfill site after damaging a power pole, firefighters said. There was dense fog in the area of Sehlem when the accident happened.
