Tehran confirms two missiles fired at Ukraine Boeing

Iran's civil aviation authority confirmed two Tor-M1 short-range surface-to-air missiles were fired at a Ukrainian Boeing 737 that was brought down earlier this month.

"Investigators... discovered that two Tor-M1 missiles... were fired at the aircraft," it said in a preliminary report posted on its website.

The authority added that an investigation was ongoing to assess the bearing their impact had on the accident, the AFP reported.

The Kiev-bound Ukraine International Airlines plane was shot down in a catastrophic error shortly after takeoff from Tehran on January 8, killing all 176 people on board.
