Iran has apologised for shooting down Ukrainian jetliner and killing all 176 persons on board.
Iran said its military “unintentionally” shot down a Ukrainian jetliner that was mistaken for a “hostile target”.
Press TV also quoted Iran’s General Staff of the Armed Forces as saying that the plane had flown close to a “sensitive military site”.
The military said it was at its “highest level of readiness” amid the heightened tensions with the United States.
“In such a condition, because of human error and in a unintentional way, the flight was hit,” the military said.
It apologised and said it would upgrade its systems to prevent future tragedies.
In a statement posted on social media, Iranian President Hassan Rouhani wrote that the country “deeply regrets this disastrous mistake”.
“My thoughts and prayers go to all the mourning families. I offer my sincerest condolences,” he said, adding that “investigations continue to identify and prosecute this great tragedy and unforgivable mistake”.
Iran had denied for several days that a missile downed the aircraft.
But then the US and Canada, citing intelligence, said they believe Iran shot down the aircraft.
The jetliner, a Boeing 737 operated by Ukraine International Airlines, went down on the outskirts of Tehran during takeoff just hours after Iran launched a barrage of missiles at US forces in Iraq.
The plane, en route to the Ukrainian capital of Kyiv, was carrying 167 passengers and nine crew members from several countries, including 82 Iranians, 57 Canadians and 11 Ukrainians, when it was shot down.
