Anti-Israel protesters' painted red hands a 'symbol' rooted in 'craze to see blood': expert

After anti-Israel demonstrators with painted red hands flooded the U.S. Capitol on Tuesday, an Israeli expert said that the red hands have a deeper meaning that is meant to signify the "emasculation of Jews" and represent a "bloody defeat."

Protesters inside the Dirksen Senate Office Building on Capitol Hill on Tuesday displayed "bloody" red palms, face forward.

Anne Bayefsky, president of Human Rights Voices, and director of the Touro Institute on Human Rights and the Holocaust, explained the meaning of the red hands to Fox News Digital after anti-Israel protesters marched through the U.S. Capitol complex.

"Palestinian hands drenched in Israeli blood are indeed a symbol - a symbol of brutality and human depravity," she said.

"No Israeli Jew, or anyone who follows the decades-long attempts to annihilate the Jewish state and everyone in it, can forget the image or the horror of what exactly those blood-stained hands meant."

Bayefsky said that the red hands became a symbol of the Ramallah Lynching of 2000, during the 2nd Intifada of the violent uprising, and premiered before celebrities wore red hand pins at the Oscars this year.

On Oct. 12, 2000, two IDF reservists, Yossi Avrahami and Vadim Nurzhitz, were lynched by a massive mob in Ramallah, West Bank, after they made a wrong turn in the Palestinian Authority-controlled region.

After rumors spread about their whereabouts at a police station, around 1,000 Palestinians gathered around the station.

One of the soldier’s wives listened by cell phone after a Palestinian butcher answered the victim’s phone, and told her, "We are now slaughtering your husband."
