US troops in the vicinity of Kobani in Syria faced an explosion caused by artillery fire. Turkish troops aimed just a few hundred meters away from the Security Mechanism Zone where they knew US soldiers to be present. While no troops were injured or withdrawn from the area, statements have warned Turkey not to pull the US into defensive actions and have called the nation out for invading Syria. Between 15 and 100 troops were present during the artillery fire and reports state that it was so intense they considered firing back in self-defense. The Turkey Defense Ministry denies that they targeted American troops, but precautions are in place to prepare for more attacks.
