The U.S. National Park Service has closed Dry Tortugas National Park in the Florida Keys after hundreds of migrants arrived on the islands over the New Year's weekend.

The NPS temporarily closed the park to public access on Monday morning after an estimated 300 migrants landed in the park, according to a news release. It said the park has seen an increase in people arriving by boat from Cuba.
