The US military carried out a second boat strike in a week in the eastern Pacific, killing four people accused of drug smuggling, as President Donald Trump's administration intensifies its crackdown at sea. The strike comes amid growing scrutiny in Congress over the legality of the campaign and demands for greater transparency. On the same day, Venezuela reacted defiantly to Trump's announcement of a "total and complete" blockade on sanctioned oil tankers, insisting crude exports remain unaffected. With US naval forces massed in the Caribbean and oil markets reacting nervously, tensions between Washington and Caracas continue to rise.
