NEW YORK (AP) — The leader of an eastern European neo-Nazi group has been extradited to the United States from Moldova following his arrest last summer for allegedly instructing an undercover federal agent to dress as Santa Claus and hand out poisoned candy to Jewish children and racial minorities, prosecutors said.

Michail Chkhikvishvili, a 21-year-old from the republic of Georgia, was arraigned Friday before a federal judge in Brooklyn on multiple felonies, including soliciting hate crimes and acts of mass violence.

He pleaded not guilty through an attorney, Samuel Gregory, who requested his client receive a psychiatric evaluation and be placed on suicide watch while in custody. Gregory did not immediately return a message seeking comment.

Prosecutors described Chkhikvishvili, who also goes by “Commander Butcher," as the leader of the Maniac Murder Cult, an international extremist group that adheres to a “neo-Nazi accelerationist ideology and promotes violence and violent acts against racial minorities, the Jewish community and other groups it deems ‘undesirables.’”

JOHANNESBURG (AP) — Rescue efforts are underway in South Africa to bring 260 workers trapped in a gold mine for a day back to the surface, the Sibanye Stillwater mining company said on Friday.

According to the company, an initial investigation showed that a sub-shaft rock winder skip door opened at the loading point and caused some damage to the mineshaft at the Kloof mine, west of Johannesburg.

“Following a detailed risk assessment, it was decided that employees should remain at the sub-shaft station until it is safe to proceed to the surface, in order to avoid walking long distances at this time,” the company said in a statement.

The National Union of Mineworkers, which represents workers at the Kloof mine, said the miners have been trapped for almost 24 hours, with the company repeatedly changing the estimated time for them to return to the surface.
