Iran said it accidentally shot down a Ukrainian jetliner this week after mistaking it for a hostile target, according to the semi-official Isna news agency.
The aircraft flew near an Islamic Revolutionary Guard Corps military site, Isna said, citing an army statement. IRGC officials will elaborate on the crash on state media, it said.

A power plant and an industrial park are in the area where the Ukrainian jet stopped transmitting its position, as well as large areas of undeveloped land, according to Google.
The plane appeared to fly on a normal path to the northwest of the airport on the same heading as the runway from which it departed, according to the flight-tracking service FlightRadar24.
It flew straight for just over two minutes after take-off, according to the company. At that point, it made a slight turn to the right and continued for another 42 seconds.
