(CNN) -- Hundreds of protesters rallied worldwide Saturday against the imprisonment and possible execution of an Iranian woman convicted of adultery.
Sakineh Mohammedie Ashtiani was originally sentenced to death by stoning, but it was put on hold earlier this month after an international outcry.
In London, protesters held posters with Ashtiani's likeness while a speaker criticized Iran's treatment of her. Many demonstrating in Trafalgar Square held signs reading, "No to Stoning. No to Executions". John Lennon's "Imagine" played in the background.
In Stockholm, Sweden, protesters chanted for Ashtiani's release while calling stoning a medieval practice that must end. They also signed a large petition calling for her release.
The case has drawn international attention. Ashtiani was convicted of adultery in 2006 and faces the possibility of execution.
