Tehran - A radiant Unidentified Flying Object was again observed in the sky of Central Sepidar in the vicinity of Bouyer Ahmad in western Iran from 19:10 to 20:30 hours local time (15:40 to 17:00 GMT) Wednesday.

Witnesses told FNA that the object has been observed for more than an hour.

In a similar incident last Monday, an Unidentified Flying Object was witnessed in the same area and at the same time.

Witnesses also said that the UFO has been as big as a ball, with a yellow ray and a bright reddish color in the center.

They also stated that the object has been flying at a very low altitude.

Officials declined to comment on the event.

Also last Wednesday, a UFO crashed in Barrez Mounts in the central province of Kerman.

Deputy Governor General of Kerman province Abulghassem Nasrollahi told FNA that the crash, which was followed by an explosion and a thick spiral of smoke, has caused no casualties or damage to properties.

He further denied earlier reports that the explosion has been the result of a plane or chopper crash, reminding that all the passing aircrafts have been reported as sound and safe.

The official further stated that investigations were underway by police and other relevant authorities in this regard.

While other reports spoke of meteors, Nasrollahi said there were no conclusive witnesses in that regard, yet he did not dismiss the possibility that the crash has been caused by a meteor.

Eye-witnesses assured that the explosion has been caused as a result of the crash of a radiant unidentified flying object onto the ground.

Meantime, an informed source told FNA that the object has been on fire and there has been thick smoke coming out of it prior to the crash, concluding that the object couldn't have been a meteor as meteors do not smoke.

The source also said that the crash has been witnessed by people in several cities, and mentioned that the rendezvous point was located 100 kilometers from the provincial capital city of Kerman.

He said that people in the city of Rafsanjan also reported to have witnessed a similar incident several days ago.

Similar crash incidents have been witnessed frequently during the last year all across Iran, and officials believe that the objects could be spy planes or a hi-tech espionage device.
