Zelensky scheduled a “telephone conversation with Iranian President Hassan Rouhani for 5 pm (1500 GMT),” Zelensky’s presidential press office said in a statement.
Tehran admitted Saturday that it accidentally downed the Ukraine International Airlines (UIA) plane, killing all 176 people on board on Wednesday, shortly after launching missiles at bases hosting US forces in Iraq.
Rouhani said that Tehran “deeply regrets this disastrous mistake”.
Zelensky earlier Saturday demanded that Iran provide “total access” to the full inquiry for Ukrainian aviation experts and security officials sent to investigate the crash on the president’s request.

Iran’s downing of the plane comes after a Malaysia Airlines flight from Amsterdam to Kuala Lumpur was shot down over eastern Ukraine in 2014 with the loss of 296 people on board.
Investigators say a Russian-made BUK missile fired by pro-Russian separatists was to blame and the trial of four people over the crash is due to start in the Netherlands in March.
Moscow has repeatedly denied any involvement in the plane’s downing.
