‘Someone just got eaten’: Beachgoers watch in horror as great white shark kills swimmer

Witnesses at a beach near Sydney, Australia, watched in horror as a swimmer was killed by a shark on Wednesday.

Video shows the gruesome attack unfold as one witness screams, "Someone just got eaten by a shark!”

"Out of nowhere we just heard like, 'Agh' And something came up and, yeah, it was just a big shark in the air, totally airborne, hit the guy very, very quick," a witness reported. "Came back down and we realized it was a shark attack on a swimmer. Just 10 meters off the rocks. We couldn't do anything about it."

"We heard a yell and turned around, it looked like a car had landed in the water, a big splash then the shark ... there was blood everywhere," said another witness.

Authorities told 9 News Australia that the "big shark" responsible for the deadly attack was likely a great white.

"Based on footage provided by the public, including eyewitness accounts, DPI shark biologists believe that a white shark, at least 3 metres in length, was likely responsible," the Department of Primary Industries said in a statement.

The fatal shark attack was reportedly the first in Sydney in almost 60 years.
