Described as a “nightmare” situation, a 55-year-old Canadian was attacked by a 7-foot bull shark while vacationing in Turks and Caicos.

A Canadian woman “attempted to engage with the animal from the shallows in an attempt to take photographs,” the territory’s environmental department said.

A Canadian woman lost both hands in a shark attack while snorkeling in Turks and Caicos. Authorities closed beaches and issued safety warnings as similar attacks occurred in recent years.
