German police commandos arrested two Somali-born terror suspects on a KLM aircraft Friday who media reports said had links to a group behind a foiled 2007 plot to attack US interests. Security forces boarded the Amsterdam-bound plane with 48 passengers on board at Cologne-Bonn at 6:55 am (0455 GMT) and took a 23-year-old Somali and a 24-year-old German citizen of Somali origin into custody, police spokesman Frank Scheulen said.
