(7:54 p.m. EST) -- A four-year old child drowned onboard Norwegian Breakaway Monday morning while the ship was en route to Florida. The child was one of two found unresponsive in the adult pool. A second child, aged six-years old, was airlifted to a hospital.

"We are extremely saddened to report that a tragedy occurred on board Norwegian Breakaway this morning," Norwegian Cruise Line said on its Facebook page. "Our emergency medical team was called and notified that two small children were rescued from the adult pool, but were unresponsive on the pool deck. The team responded immediately and quickly administered CPR to both children. The older child was then airlifted by the U.S. Coast Guard to the closest medical facility, accompanied by his grandmother and a nurse from the ship. Devastatingly, after many resuscitation attempts, the younger child passed away on board.

"We extend our deepest sympathies to the family during this extremely difficult time and are providing full assistance and support."

According to Wate.com, the website for local Tennessee TV channel 6 ABC, the rescue occurred off the coast of North Carolina and the child was transported to a hospital in New Bern. The site further reports the child is in stable condition.

It is unclear whether the children were related.

Breakaway was on the second day of a weeklong cruise from New York to Florida and the Bahamas.
