CAPE GIRARDEAU, Mo. (AP) - A federal judge is giving the go-ahead to the Army Corps of Engineers' plan to intentionally break a Mississippi River levee in southeastern Missouri. The break could happen as early as this weekend to spare a flood-threatened Illinois town just upriver. Friday's ruling in Cape Girardeau turns back Missouri's bid to block the corps from blasting a hole in the Birds Point levee in Mississippi County, just south of Cairo, Ill. Missouri argued the floodwaters would ruin farmland and damage about 100 homes.
