WASHINGTON, D.C. (BNO NEWS) — B’nai B’rith International, the oldest and most widely known Jewish humanitarian, human rights and advocacy organization, had condemned the shooting incident at the U.S. Holocaust Memorial Museum on Wednesday. The shooting left one security officer dead, while the gunman remains in critical condition after being shot by other guards.

The organization called the shooting shocking and deeply disturbing on several counts. “B’nai B’rith is appalled that the shooting took place in a building dedicated to remembering the worst genocide in history,” Sharon Bender, who is a spokeswoman for the organization, said in a statement.

“The museum was founded in the hope that, by remembering the Shoah, it will never be repeated. For it to be the site of a shooting by a man identified as anti-Semitic and a white supremacist is testimony to the need for humanity to take actions to prevent hate incidents from ever happening again,” Bender said.

The gunman was identified by authorities as James W. von Brunn, who is a known white supremacist who runs a website with anti-Semitic writing. “Our thoughts and prayers go to the family of Officer Stephen Tyrone Johns, who was killed in the attack,” Bender added.
