Three British teens have left their home country to join ISIS forces over the weekend, CBC reports.
Shamima Begum, 15, Kadiza Sultana, 16, and an unnamed 15-year-old flew from London to Turkey last Tuesday without notifying family or friends.
Police are “extremely concerned for their safety,” seeking help through social media to encourage their safe return home, “back to their families who are so worried about them,” according to the CBC.
