All 168 people on board a passenger plane were killed when the aircraft crashed in northwestern Iran, according to Iran’s government-owned Press TV. Ten members of the country’s youth judo team were aboard the plane, according to Tabnak, a Web site associated with opposition politician Mohsen Rezaie. The plane “disintegrated into pieces,” said Col. Masood Jafari Nasab, security commander of the city of Qazvin, close to the crash site. Video of the crash site showed a huge crater in the earth scattered with charred pieces of the plane and tattered passports. The Russian-made Tupolev plane went down near the village of Jannatabad near Qazvin at 11:33 am on Wednesday, the station reported.
