An American Indian tribe sued some of the world's largest beer makers Thursday, claiming they knowingly contributed to devastating alcohol-related problems on South Dakota's Pine Ridge Indian Reservation.

The Oglala Sioux Tribe of South Dakota said it is demanding $500 million in damages for the cost of health care, social services and child rehabilitation caused by chronic alcoholism on the reservation, which encompasses some of the nation's most impoverished counties.

The lawsuit filed in U.S. District Court of Nebraska also targets four beer stores in Whiteclay, a Nebraska town near the reservation's border that, despite having only about a dozen residents, sold nearly 5 million cans of beer in 2010.

Tribal leaders and activists blame the Whiteclay businesses for chronic alcohol abuse and bootlegging on the Pine Ridge reservation, where all alcohol is banned. They say most of the stores' customers come from the reservation, which spans southwest South Dakota and dips into Nebraska.
