A 4-year-old child died after being pulled unresponsive from a swimming pool on a Norwegian Cruise Line ship off the coast of North Carolina on Monday, cruise line and Coast Guard officials said. Crew members were able to revive a 6-year-old boy also found in the pool. He was airlifted to a hospital, where his condition was unknown. The two children were found in the morning on the Norwegian Breakaway, the cruise line said in an announcement on its Facebook page.
