Iran announced Saturday that its military “unintentionally” shot down the Ukrainian jetliner that crashed earlier this week outside Tehran, killing all 176 aboard, after the government had repeatedly denied Western accusations that it was responsible.
The plane was shot down early Wednesday, hours after Iran launched a ballistic missile attack on two military bases housing US troops in Iraq in retaliation for the killing of Iranian general Qassem Soleimani in an American airstrike in Baghdad. No one was wounded in the attack on the bases.
A military statement carried by Iranian state media said the plane was mistaken for a “hostile target” after it turned toward a “sensitive military center” of the Islamic Revolutionary Guard Corps. The military was at its “highest level of readiness,” it said, amid the heightened tensions with the United States.
