German authorities have announced the arrest of two youths accused of planning to detonate a small truck at a Christmas market in western Germany, in an attack reminiscent of tactics used by the terrorist organization "ISIS." The first teen (15 years old) was arrested on Tuesday in Burscheid, a town near Cologne, and a court in Leverkusen ordered his detention yesterday pending a potential indictment. Another teenager was arrested in Brandenburg, eastern Germany. Officials state that the 15-year-old wrote in a chat group about the attack plans. Prosecutors in Düsseldorf reported that he and the other suspect are accused of conspiring to attack the Christmas market in Leverkusen, a city located in North Rhine-Westphalia in western Germany, in early December using fuel to blow up a small truck. The teen claims he obtained gasoline for the plan, according to a statement from the public prosecutor's office. It is alleged that the two suspects planned to leave Germany together after the attack to join "ISIS" in Khorasan, a branch of "ISIS" active in Afghanistan and surrounding areas.
