The most radical jihadist group fighting in Syria on Sunday killed a 102-year-old man along with his whole family in the heart of the country, a monitoring group said. The 102-year-old was shot dead in his sleep, with the Islamic State of Iraq and the Levant (ISIL) also killing his son, his grandson, his great-granddaughter and her mother, said the Syrian Observatory for Human Rights. All the victims were Alawites, members of the same offshoot of Shiite Islam as Syria's President Bashar al-Assad. Rooted in Al-Qaeda in Iraq, ISIL is the most extremist group fighting in Syria's war.
