An Iranian commercial aircraft carrying 66 people crashed on Sunday in southern Iran, a semi-official news agency reported. There was no immediate word on casualties.
The ATR-72, a twin-engine turboprop used for short-distance regional flying, went down near the remote mountain town of Semirom, some 620 kilometers (390 miles) south of the capital, Tehran, the semi-official Fars news agency said.
Fars said the plane was flying from Tehran to the southern Iranian city of Yasuj, some 780 kilometers (485 miles) south of the Iranian capital.
Authorities said the plane was flown by Aseman Airlines, a semi-private air carrier headquartered in Tehran that specializes in flights to remote airfields across the country. It also flies internationally.
Under decades of international sanctions, Iran’s commercial passenger aircraft fleet has aged, with air accidents occurring regularly in recent years.
