"We do not confirm claims about the found pieces of wreckage of the crashed plane. We have not received any information about this," the source said.
A group consisting of seven French specialists will arrive in Tehran later on Monday to search for debris, the source continued.
"The Canadian manufacturer of the plane's engines has expressed its readiness to send a team of specialists for help upon authorization from Tehran," the source pointed out.
The statement comes immediately after a source told Sputnik that experts had found some debris of the Iranian passenger plane that crashed on Sunday.
The plane carrying 60 passengers and six crew members crashed near the city of Semirom the day before during a flight from Tehran to the southwestern city of Yasuj.
All 60 passengers and six crew members died following the plane crash.
