NEW YORK—An argument between two groups of teenagers riding the New York City subway exploded into deadly violence Monday when a shooting started after the train’s doors opened at a station, killing a man and wounding five others.
The gunfire broke out on an elevated train platform in the Bronx at around 4:30 p.m., a time when stations throughout the city are filled with kids coming home from school and many workers are beginning their evening commute.
