Earlier, the head of European diplomacy, Josep Borrel, expressed concern about the temporary detention of Mackair.

On Sunday, January 12, Tasnim reported that the British ambassador was detained in Tehran in connection with protests after Iran pleaded guilty to the downed Ukrainian plane.

Makair said he came to the memorial service in connection with the crash of a Ukrainian passenger plane in order to pay tribute to the victims.
