DAVIS, Okla. (AP) - Two foreign exchange students who attended school in Texas have drowned at a popular tourist destination in southern Oklahoma.

Authorities say the men died Tuesday at Turner Falls near Davis, 70 miles (113 kilometers) south of Oklahoma City.

Police say one man was struggling in a pool near the falls when a friend jumped in to help and neither resurfaced. They weren't wearing life jackets.

The men were natives of India who attended the University of Texas at Arlington. The Medical Examiner's Office didn't immediately respond to an email seeking their names.

Two other people, a 27-year-old woman and a 39-year-old man, drowned at Turner Falls during the July Fourth holiday. Both were also natives of India.

Officials say a 4-year-old boy also drowned Tuesday in a central Oklahoma pond.
