Syrian rebels' activities

"Militants placed explosives at the shrine of Sheikh Eissa Abdelqader al-Rifaiy in the rebel-held town of Busaira, 45 km (30 miles) east of the provincial capital of Deir al-Zor, and detonated them on Sunday morning, they said." "Several graves and other sites belonging to the Sufi sect, a mystical school of Islam opposed by puritanical Salafists from which al Qaeda draws its ranks, have been burnt or destroyed in the province in the past few months, opposition sources said."
