SAN SALVADOR—President Nayib Bukele on Sunday declared himself winner of El Salvador’s national elections in a landslide, claiming he captured more than 85 percent of the vote—even though electoral officials have not released any results.
Mr. Bukele was the heavy favorite to win another five-year term as voters largely cast aside concerns about erosion of democracy to reward him for a fierce gang crackdown that improved security in the Central American country.
