Nicolás Maduro shares photos from New York prison: "We are standing firm"

In the two photographs, Venezuela's deposed leader Nicolás Maduro is wearing a gray tracksuit and making peace signs with his hands.

The photos surfaced two days after Maduro's successor, Delcy Rodriguez, announced a "historic" oil agreement allowing the US to operate oil fields in Venezuela.

Maduro and his wife, Cilia Flores, were seized in Caracas during a US military operation in January. They are being detained in a Brooklyn, New York jail on drug trafficking and firearms possession charges, which they deny.
