The mothers of three American hikers who are being detained in Iran held a protest in Manhattan on Friday to mark the one-year anniversary of the imprisonment of their children.

Nora Shourd, mother of Sarah Shourd: “The place where we are here today, if people are not aware, is the Iranian mission, which is the closest we can get to speaking to someone in the Iranian government directly, and that’s why we’re here today. It’s been very frustrating for us all along to not be able to talk to someone who’s directly responsible for holding our kids. You know, this is as close as we can get, but we’re knocking on the door symbolically here, too.”
