For Mojdeh and her husband, the question of US intervention in Iran is personal.

In early January, they travelled from their home in Washington, DC to Tehran to visit family - expecting a short, routine trip. Instead, protests spread, flights were cancelled and they found themselves stranded in a city that no longer felt predictable.

"Life was on pause," Mojdeh said, especially at night, when the internet and even phone networks went dark.

They did not plan to protest. But on the nights of 7 and 8 January, she said, it was impossible to remain uninvolved.

"If you left your house, you saw it," she said. The BBC has changed her name to protect her and her husband's identities.
