The fragile peace in Syria's Aleppo is exacerbated by the high concentration of terrorists to the west and north of the city, the Russian Defense Ministry's spokesman for ceasefire and humanitarian issues in Geneva, Col. Alexander Zorin, said.
"The peace that you see in Aleppo is fragile. To the west and the north of the city, we are recording a constant and high concentration of extremists," Sputnik cited the spokesman as saying.
Syria's civil war between government forces and a wide range of insurgents, including opposition groups and terrorists, such as al-Nusra Front and ISIS, has raged for some five years and has claimed hundreds of thousands of lives. Aleppo was liberated and fully retaken by the government in late December.
