Southern Syria ceasefire holds despite sporadic violations
There were also reports of scattered exchanges of fire in Quneitra province, although no casualties were reported in any of the incidents, the rights monitor said.
"There are minor violations that do not affect the ceasefire," said Observatory director Rami Abdel Rahman.
"In general there is quiet in the three provinces."
Last week, the Syrian regime announced a unilateral ceasefire in southern Syria ahead of peace talks in the Kazakh capital, Astana.
Hours after the announcement was made, rebel groups and witnesses said Syrian regime airplanes dropped barrel bombs in the southern city of Daraa, Naima to its east, and surrounding countryside.
Opposition figures had expressed doubts about the Syrian regime's announced ceasefire plan, describing it as a ploy to drag the opposition to Astana.
"The regime is lying and the Russians are lying and are not serious in achieving a ceasefire," Major Issam al Rayes, spokesman for the Southern Front, a coalition of Western-backed FSA rebel groups, said at the time.
Syria's conflict evolved from a bloody crackdown on protests in 2011 to a devastating war that has drawn in world powers, including Russia and a US-led international coalition.
