Strong waves at Tanah Lot swept a group of 11 relatives out to sea on Sunday as they were performing a ritual cleansing; one of the group drowned, the family said.

“We were praying in front of the temple, and it was low tide, but suddenly a large wave crashed down on us and swept us out,” family member Dayu Armini told reporters, referring to the famous Tanah Lot temple perched atop a rock on the southwest coast of Bali.

Ten of the group managed to get back to shore, but one, a 24-year-old man, drowned, she said.
