Remember the UFO sightinga nd crash in Iran?

Upto a year ago or maybe less there was a report of UFO sighting and crash/explosion in Iran. I only saw this from Iran news sources and the Art Bell show I believe mentioned this. Well I want to do further research on it since the said location was a test sight for Iranian military and I had read that after this reporting a person went and took samples to find evidence of a detonator used in nuclear test missles. I figure if Iran is testing such things we are not making it public. Reminds me of when Japanee bomb hot air baloons were sent here and we said nothing until someone got blown up (2 kids).

Please add all you know.
