An Iranian semi-official news agency is reporting that a drone belonging to the Iranian navy has crashed in the southern port town of Jask.

The Sunday report by Tasnim, which has ties to the military, said thick smoke rose from the crash site in downtown Jask, some 930 miles southeast of the capital Tehran. The report gave no additional details.
