Armed police officers boarded a jet just minutes before takeoff Friday and arrested a pair of ethnic Somalis, saying they found a suicide note from the men that claimed the pair wanted to fight in a holy war and die in a terrorist attack. A 23-year-old Somali and a 24-year-old German born in Somalia boarded the KLM Flight 1084 without incident after the surprise early morning raid at Cologne-Bonn Airport, police said. Police said authorities did not think the men planned to hijack the plane.
