because they are on a tape with other men.
TEHRAN (AFP) - Two Iranian sisters convicted of adultery face being stoned to death after the supreme court upheld the death sentences against them, the Etemad newspaper Monday quoted their lawyer as saying. The two were found guilty of adultery -- a capital crime in Islamic Iran -- after the husband of one sister presented video evidence showing them in the company of other men while he was away.
The pair admitted they were in the video presented by the husband but argued that there was no adultery as none of the footage showed them engaged in a sexual act with other men.

I can't believe this can happen in the 21st century...but then again Iran (according to its own calendar) is in the year 1386, so it has 6 centuries to become a normal civilized country.
