El Salvador had more homicides in March than any other single month in a decade, a dark milestone that some attribute to the collapse of a gang truce and one that could mark a trend of greater violence to come.

Data from the National Civil Police show 481 homicides recorded last month, or more than 15 a day. April’s start is no better, with 73 killings reported in the first five days. At this rate, El Salvador is on pace to surpass Honduras as the deadliest peacetime country in the world.
