Iranian state television says 13 of the 16 people killed in Friday's plane crash in northeastern Iran were members of the crew. Saturday's report quotes Iran's civil aviation spokesman, Reza Jafarzadeh, as saying the plane's high speed while landing was a key cause of the crash. The Russian-made Ilyushin-62 plane, carrying 153 passengers and crew, skidded off the runway and hit a wall Friday while landing in the northeastern city of Mashhad, killing 16 people. Earlier, officials said 17 were killed. Among the dead was the manager of the privately owned Aria Airlines, which leased the plane from Kazakhstan. The TV report said nine of the dead crew members were Kazakhs and Aria's license has been suspended until the crash is investigated.
