Five members of the Ukrainian group Femen tore off their clothing and shouted slogans against what they called court-sanctioned murder during the event at Kiev’s Ukrainian House convention centre, which featured hundreds of Ukrainian and Iranian dignitaries.
“Don’t kill women!” one Femen activist shouted.
Security guards expelled the protesters after a scuffle.
A Ukrainian official later apologised to the audience for the disturbance, saying “at least we don’t have to be ashamed about what we have on display.”
The case of Sakineh Mohammadi-Ashtiani, who has been sentenced to death by stoning, has sparked international protests. Iranian authorities said her case is under review.
