Fighting is raging on several fronts amidst U.S.-led airstrikes on Iraq and Syria. At least 16 fighters with the al-Qaeda-linked Nusra Front were reportedly killed Sunday after attacking a Hezbollah position inside eastern Lebanon, close to the Syrian border. A female Kurdish suicide bomber reportedly killed a number of Islamic State fighters in the besieged Syrian town of Kobani. But the Islamic State is reportedly threatening to capture Kobani after several weeks of fighting, sparking fears of a massacre if it takes control.
