Dozens of cruise ship passengers were involved in an all-out brawl in a nightclub on a ship as it sailed through international waters headed for New York City overnight into Tuesday, according to reports. 

Security for the Carnival Magic tried to intervene when the physical fight escalated to as many as 60 people but eventually had to call in the Coast Guard to help escort the ship back, according to the New York Post. 

The ship arrived Tuesday morning with New York police waiting as it docked.

It's unclear if anyone was arrested or if New York or New Jersey authorities would handle it or another jurisdiction since it may have happened over international waters.
