The IRNA news agency quoted Tehran’s military prosecutor, Gholamabbas Torki, saying that the recorder had been sent to France, without giving further details. He said the recorder was “physically damaged” and that the data could only be recovered with “sophisticated” technology.
He said Iranian experts were unable to acquire the necessary converter due to US sanctions.
Iran accidentally shot down the Boeing 737-800, killing all 176 people on board, after mistaking it for an incoming missile. Iran was preparing for a counterattack after launching missiles at US bases in Iraq in response to the murder of its commander-in-chief, General Qassim Soleimani, in an American strike earlier in January.
Since then, it has been negotiations with Ukraine, Canada and other nations that had citizens on board the plane and that demanded a thorough investigation.
Iran initially attributed the accident to technical problems, and did not admit to shooting the plane until a few days later.
