A South Korean teen is feared to have joined Islamic State during a trip to Turkey, the country's police reported in a briefing on Thursday.
Authorities said that the 18 year old, referred to only by his last name Kim, was vacationing in Turkey with an older family friend as his guardian when he disappeared. He was last seen in the city of Kilis, close to the Syrian border, the Los Angeles Times reported.
An additional report by CNN on Friday said that the teen disappeared from the pair's Kilis hotel after breakfast, making two phone calls to unknown Turkish phone numbers before entering a car with Syrian plates, as recorded on security footage.
If confirmed, this would mark the first incident of a South Korean national joining the ranks of the extreme Islamist group.
Police are continuing their investigation and so far, have uncovered evidence that Kim researched Islamic State online and made public social media statements about his desire to join their ranks.
