The U.S. Coast Guard rescued a young child, but another drowned in a swimming pool onboard NCL Breakaway on Monday afternoon.

The Coast Guard received the call around noon, regarding two children who may have drowned on the Norwegian Cruise Ship Breakaway.

Coast Guard officials say the incident involved a 6 year old and a 4 year old.

Breakaway medical staff were able to resuscitate the older child. The Coast Guard says the 4 year old was pronounced dead at the scene.

A Norwegian Cruise Line statement said: "We are extremely saddened to report that a tragedy occurred on board Norwegian Breakaway this morning," 

"Our emergency medical team was called and notified that two small children 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, 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.

"The family is in our thoughts and prayers and we ask that you please keep them in your thoughts and prayers as well"
