On January 8, a passenger plane of Ukraine International Airlines Boeing 737 crashed shortly after taking off in the Iranian capital. The victims of the crash were 176 people.

On January 11, the Iranian General Staff said that the liner was shot down accidentally as a result of a human error.

According to Iranian Foreign Minister Mohammad Javad Zarif, a mistake was made during the crisis, "provoked by US adventurism."

President Hassan Rouhani noted that those responsible for the crash will be held accountable.

Zelensky, in turn, said that Ukraine expects Iran to fully plead guilty for the downed Ukrainian plane, as well as bring the perpetrators to justice, formally apologize and pay compensation.
