WATERLOO, Neb. (AP) — A Platte River ice jam near Omaha has broken up on its own, so officials have canceled plans to attack it with dynamite.

The 1½-mile-long jam had backed up river water in western Douglas County, just west of Omaha, and parts of Saunders County, threatening homes, well fields and a National Guard camp.

But the jam broke up on its own by 9:45 a.m. Thursday.
