"We've found confirmations that the real aim of 'the three' was to give terrorists a break, restore their strength, prolong the bloodshed on the Syrian soil, thus impeding the process of the political settlement," the ministry's spokeswoman Maria Zakharova said.
According to the spokeswoman, the Syrian forces have found containers with chlorine and smoke bombs, produced in Germany and the UK.
"In the liberated territories of Eastern Ghouta, the Syrian government troops have found containers with chlorine — the most terrible type of chemical weapons — from Germany, as well as smoke bombs produced — attention! — in [UK town of] Salisbury," Zakharova said at a weekly news briefing.
"It is difficult to even comment on this fact in any way, as it is so frightening and undermining the belief in the humanity of certain countries," Zakharova added.
Speaking further, Zakharova noted that Russia has information that al-Nusra* militants, supported by the US, was creating an autonomy in southern Syria.
Last week, the United States, France, and the United Kingdom launched strikes on a number of targets in Syria in response to the alleged chemical attack in Douma.
The launches came the same day that the OPCW mission was set to start the probe into the alleged chemical weapons use in Douma, which the West had immediately blamed on Damascus.

According to the Russian Defense Ministry, the three countries fired over 100 cruise and air-to-surface missiles, most of which were shot down by Syrian air defenses. According to Damascus, which has repeatedly said that it eliminated its chemical weapons stockpiles, the attack damaged Syrian infrastructure and left three civilians injured.
Russian President Vladimir Putin stated on Saturday that the strikes had been carried out in violation of the norms and principles of international law.
