Venezuelan opposition leader María Corina Machado said Friday that she is focused on an orderly transition of power in her country should President Nicolás Maduro leave power and that she is confident Venezuela’s police and armed forces would not oppose such a transition.

The United States has announced new sanctions on shipping companies and vessels it says help move Venezuelan oil, putting more pressure on a major prop of President Nicolas Maduro’s regime a day after it seized a sanctioned tanker likely carrying millions of dollars’ worth of oil off the country’s coast.
