The Latest: German security chief sees no terrorist factor in plane crash

Germany's top security official says that there are "no indications of any kind of terrorist background" to the Germanwings crash, which a French prosecutor has blamed on the German co-pilot.

Interior Minister Thomas de Maiziere said German authorities checked intelligence and police databases on the day of the crash, and Lufthansa told them that regular security checks also turned up nothing untoward on the co-pilot. Tuesday's crash in the French Alps killed 150 people.
