The United States military has killed four people after striking a suspected drug-smuggling boat in the Caribbean Sea, US Southern Command (SOUTHCOM) confirmed. The strike targeted what officials described as a fast-moving vessel travelling along known narco-trafficking routes, with intelligence said to have confirmed the boat's involvement in drug smuggling. The operation is part of "Southern Spear," a broader US military campaign of air strikes against suspected drug-trafficking vessels in the Caribbean and eastern Pacific, launched under President Donald Trump's stated goal of waging war on cartels he considers a threat to national security.
