WASHINGTON — The Biden administration announced new sanctions on Friday against Cuba’s national revolutionary police and its top two officials as the U.S. looks to increase pressure on the communist government following this month’s protests on the island. The Police Nacional Revolcionaria and the agency’s director and deputy director, Oscar Callejas Valcarce and Eddie Sierra Arias, were targeted in the latest sanctions announced by the Treasury Department’s Office of Foreign Assets Control. The police are part of Cuba’s interior ministry, which was already the subject of a blanket designation by the Trump administration back in January.
