In this Friday, Oct. 26, 2012 photo, Syrian rebel fighters take cover as a Syrian army sniper aims over a destroyed mosque in Tarik Al-Bab, southeast of Aleppo, Syria. Activists say Syrian troops have shelled rebel-held areas and clashed with anti-government gunmen in several parts of the country despite an internationally mediated cease-fire. The Britain-based Syrian Observatory for Human Rights and the Local Coordination Committees report shelling and shooting mostly in the northern province of Aleppo, the eastern region of Deir el-Zour, Daraa to the south and suburbs of the capital Damascus.
