Two Iranian sisters convicted of adultery face being stoned to death after the supreme court upheld death sentences against them, Iranian media have reported.

The penal court of Teheran province had already sentenced the sisters, identified only as Zohreh, 27, and Azar, to stoning, the newspaper said.

The Etemad newspaper quoted Jabbar Solati, their lawyer, as saying that the sisters had initially been tried for “illegal relations” and had received 99 lashes. However, they were convicted of “adultery” in a second trial for the same incident.

The pair admitted they were in the video but argued there was no adultery as no scene on the video showed them engaged in a sexual act.
