18 have been murdered since the beginning of the year: travel warning to one of the most beautiful destinations in the world Israel today. The US embassy in the islands also issued a security alert amid concerns for the safety of tourists, which reached a boiling point.

"Murders occurred at all hours of the day, including in broad daylight on the streets," the embassy wrote in a statement. The warning comes several months after a 74-year-old tourist drowned during a trip while on a local boat.
