Deposed Venezuelan leader Nicolas Maduro and his wife Cilia Flores have been taken into US custody and pleaded not guilty to charges including drug trafficking and narco-terrorism conspiracy. The US described the seizure as a law enforcement operation, while Maduro called it a kidnapping and a "prisoner of war" situation. Both face potential life sentences, and bail is considered unlikely given the severity of the charges. Their next court hearing is scheduled for March 17 in New York City.
