A six-year-old boy has been rescued after being trapped under a sand dune in Indiana for more than three hours, according to US media reports.

The child was in a critical condition on Saturday but was responding well to treatment, hospital officials said.

He reportedly fell into a hole at Mount Baldy on the shores of Lake Michigan on Friday evening and was buried under 11ft (3.4m) of sand.
