The Aseman Airlines plane that disappeared from radar screens yesterday is still lost, rescue teams are yet to find it. The plane got lost yesterday 50 minutes after the start of its journey from Tehran to Yasuj. The plane most likely went down in the mountains which makes it difficult to find the wreckage.

The temperature on the ground when the first rescue teams were sent out was -16 degrees Celsius according to a local Red Crescent official.

"We are facing a total enigma. We do not know anything about the crash," said Transport Minister Abbas Akhound.

The missing plane is a 24-year-old twin-engine turboprop ATR 72 that had been sent back to service just three months ago after being in storage for six years.

Search for the missing plane continues, but nobody expects to find any survivors.
