Iranian state TV, citing a military statement, says the country ‘unintentionally’ shot down a Ukrainian jetliner, killing all 176 aboard.

The statement came Saturday morning and blamed “human error” for the shootdown.

Meanwhile, Iranian President Hassan Rouhani in a tweet said that an “Armed Forces’ internal investigation has concluded that regrettably missiles fired due to human error caused the horrific crash of the Ukrainian plane and death of 176 innocent people.”

This "great tragedy" and "unforgivable mistake" are being investigated, he said in a tweet. 

“The Islamic Republic of Iran deeply regrets this disastrous mistake. My thoughts and prayers go to all the mourning families. I offer my sincerest condolences,” he added.
