Nicolás Maduro rejected new torture allegations during a court appearance in New York on Thursday. The claims form part of a rewritten drug-trafficking indictment against the former Venezuelan president and his wife, Cilia Flores.

Judge Alvin K Hellerstein entered not-guilty pleas for both defendants. Maduro, speaking through an interpreter, criticised the indictment when asked twice to enter a plea. Flores also denied the charges through an interpreter.

The indictment alleges that the couple led a state-backed campaign of repression in which scores of people, including three Americans, were tortured. It accuses Maduro of recommending methods and receiving updates about victims, while Flores allegedly helped develop the system and ordered the torture of particular people.

US troops seized the couple from their Caracas home in January. Maduro, who had been Venezuela’s president since 2013, has also faced a years-long International Criminal Court investigation into alleged crimes against humanity linked to a crackdown on opponents. He has denied wrongdoing.
