An Israeli military officer froze to death while hiking in Chile, the Israel Defense Forces said Saturday.

Lt. Noam Rubenstein, 22, was backpacking in South America on a private trip when she died over the weekend.

She apparently broke her ankle while hiking through the mountainous Cerro Castillo National Reserve.

Her companion, another Israeli, left to get help, but when rescuers reached her several hours later, she was already dead.

According to her Facebook profile, Rubinstein was a native of Misgav, in the north of Israel, and was living in Jerusalem.

Chilean police said they were opening an investigation, Ynet news reported, citing local media.

The Israeli Foreign Ministry said it was working to bring her body to Israel for burial.
