A ceasefire, agreed by Russia and the United States on Monday, came into effect overnight and has been upheld by 97 militant groups, according to the UN Syrian envoy. UN-listed terrorist groups are not part of the arrangement.
"We are in for a colossal work. It will take years and yeas to rebuild what terrorists have destroyed," Shaaban said in a televised interview on Russia’s Vesti v Subbotu weekly news program.
The Syrian government confirmed last Tuesday it was ready to halt military actions in accordance with the Russia-US deal. Some opposition groups were initially skeptical about the ceasefire but eventually signed up to it.
