The War Department’s inspector general announced a review of whether the U.S. military’s strikes against suspected drug smugglers in the Caribbean followed the required targeting process.

Last September, the Pentagon began what it dubbed Operation Southern Spear, and since its origin, U.S. Southern Command has targeted nearly 60 small boats in the Caribbean Sea or eastern Pacific Ocean that it says were attempting to smuggle drugs into the country, killing nearly 200 people in those strikes.
