The head of Lebanon's Hezbollah on Monday vowed his Shiite movement would keep fighting in Syria alongside President Bashar al-Assad’s forces until the Islamic State group and Al-Qaeda jihadists are defeated. 

"We went to Syria to help keep the country from falling into the hands of Daesh and Al-Nusra Front," Hassan Nasrallah told Lebanese channel Al-Mayadeen, referring to IS and Al-Qaeda’s Syria branch. "So long as we have a responsibility to be there, we will be there."
