NEW YORK (AP) — An explosion on a boat carrying raw sewage that was docked on the Hudson River in New York City killed a longtime city employee Saturday, authorities said.

Another worker on the city-owned Hunts Point vessel was injured and taken to the hospital after the blast around 10:30 a.m. near the North River Wastewater Treatment Plant, according to city Fire Department Deputy Assistant Chief David Simms. A third worker refused medical treatment.
