SANLIURFA, TURKEY - SEPTEMBER 28:   Smoke is seen rising from the Syrian Kurdish town of Kobani following an explosion that was followed by further fighting, which saw IS fighters shoot into Turkey for the first time on September 28, 2014 south of Sanliurfa, Turkey. Islamic State (IS, also called ISIS and ISIL) fighters are reportedly advancing with heavy weaponry on the strategic Kurdish border town of Kobani (also called Ayn Al-Arab), which they have surrounded on three sides. Several hundred thousand refugees are reportedly in Kobani and aid agencies are bracing for a massive exodus into Turkey.  (Photo by Carsten Koall/Getty Images)
