New Jersey State Police say a small boat carrying four duck hunters has capsized in the Delaware River, but all four swam to safety.

Trooper James Hearne says the boat left Pennsylvania's Bucks County early Saturday and capsized in the river around 6:30 a.m. He says two of the men swam to an island in the middle of the Delaware while the other two swam to the river's New Jersey shore.

Bucks County emergency crews responded. Hearne says three of the men were taken to the Hunterdon Medical Center and one was treated on the scene for exposure to water and the cold. Hearne says all are expected to be OK.
