"The leaders exchanged opinions on the situation in Syria including the
accusations against Damascus by a number of Western countries of using chemical
weapons. The Russian side stressed the unacceptability of provocation and
speculation on this matter,” the Kremlin said in a statement.
An alleged chemical attack on Saturday in the militant-held town of Douma in Eastern Ghouta reportedly left dozens dead.
Eastern Ghouta, which is home to nearly 400,000 people, fell to multiple militant groups in 2012, months after Syria plunged into crisis and has since served as a launch pad for fatal attacks against residents and infrastructure in Damascus.
Damascus, in a statement released late on Saturday, strongly rejected the allegation of using chemical munitions and said that the so-called Jaish al-Islam Takfiri terrorist group, which has dominant presence in Douma, was repeating the accusations "in order to accuse the Syrian Arab army, in a blatant attempt to hinder the Army’s advance.”
