Tahmineh Milani, an Iranian director and filmmaker, published a video on her Instagram account showing that a threatening message was written on the wall of her house.

On Ms. Milani’s house wall, it says “In memory of the children of Minab,” and part of the text refers to an attack on “a wedding in Sirik,” using the phrase “this is the last warning.”

In her explanation of the video on her Instagram, Tahmineh Milani wrote: “On my birthday night, some unknown people, at night, gave me a gift. This morning, the 101 precinct joined, so that the perpetrators could be arrested. Right now, we are following up on legal actions. The interesting thing is that these people have no knowledge of me or of my social activities. I have repeatedly posted stories and posts in order to condemn the explosion at the wedding in Sirik, and to condemn the killing of innocent children of Minab.”
