Russian authorities are searching for a suspected female terrorist.
They are concerned she may be used for an attack within an Olympic Zone in Sochi.
She is the widow of an Islamic Militant killed last year by Russian security forces.
Officials call female terrorists “Black Widows.”
They say some seek to avenge the deaths of their husbands.
They are considered to be difficult to pick out in a crowd because security experts say they don’t fit the “stereotype” of an Islamic Militant.
These so-called “Black widows” can also alter their appearance with clothing and make-up.
