An Iranian passenger plane carrying 105 people crashed into a mountain while trying to land in western Iran Tuesday, and there was no sign of any survivors, a witness told Reuters. He quoted doctors at a hospital as saying they had received the bodies of at least 30 people killed in the crash of the Russian-built Tupolev-154 near the city of Khorramabad. The plane, belonging to Iran Air Tours, an affiliate of the state carrier Iran Air, was flying from Tehran to Khorramabad when it disappeared off radar screens southwest of the city.
