Iran is no longer sharing evidence from the investigation into the Ukraine airliner crash with Ukraine after audio from the investigation was leaked by Ukrainian media, the director in charge of accident investigations at Iran’s Civil Aviation Organization was quoted as saying on Monday.

The audio file was part of the evidence that was given to Ukrainian experts as part of the joint investigative team’s examination of the crash, Iran says, according to Reuters.

"The technical investigation team of the Ukrainian airline crash, in a strange move, published the secret audio file of the communications of a pilot of a plane that was flying at the same time as the Ukrainian plane," Hassan Rezaifar said, according to the semi-official Mehr news agency.

"This action by the Ukrainians led to us not sharing any more evidence with them."

As UNIAN reported earlier, on February 2, President of Ukraine Volodymyr Zelensky said the Ukrainian side had an air traffic control tower communications proving that Iran knew all along that the Ukrainian UIA plane had been downed by a missile.

From the leaked audio released by Ukrainian media, it's clear that the pilot of Iran's Asaman Airlines saw both a missile launch and an explosion.

According to Zelensky, Ukraine received the recording "without access to the control room and without black boxes."
