A masked performer impersonating U.S. President Donald Trump appeared behind bars in a mock prison cell above Tehran’s busy Tajrish Square on Wednesday, drawing crowds of onlookers. Dressed in a dark suit and red tie, the actor paced inside the cell as passers-by stopped to watch and film. The installation was part of a billboard carrying the slogan “It is a crime not to see this scene”. It comes a day after Iran told Pakistan’s army chief there would be no talks with Washington until Tehran’s demands were met, according to Iranian media.
