Roatan, Honduras

(3:20 p.m. EDT) -- A couple on their honeymoon were involved in an accident while on a Royal Caribbean ziplining excursion in Roatan, leaving the husband dead and the wife seriously injured.

Royal Caribbean confirmed the incident to Cruise Critic.

"On July 5, two guests from Israel sailing on Allure of the Seas were involved in a zipline accident while ashore in Roatan, Honduras. Both guests were transported to a local hospital for treatment, where one guest unfortunately died from his injuries. Our Care Team is providing support and assistance to the guests' family and friends. Our thoughts and prayers are with the couple, and we will continue to do our very best to assist them."

According to the Washington Post, the newlywed couple were ziplining when the 27-year-old woman became stuck partway. While she was still there, her husband came down and the two collided. The 24-year-old man was conscious and alert but later died at the hospital from his injuries. His wife was transported by air to a hospital in the U.S.

Honduran authorities have launched an investigation, and Royal Caribbean has suspended the excursion pending results of the investigation.

Allure of the Seas was five days into a seven-night itinerary that had departed from Fort Lauderdale on July 1.
