The watchdog also confirmed that Russian diplomats are organising a briefing on Thursday in The Hague for OPCW member nations and would "bring some Syrians to speak about the reported Douma incident".
On Tuesday, Russia's Kommersant newspaper, citing sources, said that S-300s would be given - not sold - to Syria and that issues surrounding the transfer "have practically been resolved".
"We promised not to do it around a decade ago at the request of our partners, and we took into consideration their argument that this would destabilize the situation, despite this [S-300] being a purely defensive system", Lavrov said. They will identify themselves in the video. The three western countries responded with strikes at several Syrian chemical facilities, according to ITV News. "If they're used against us, we'll act against them".
The event is part of an ongoing clash of narratives between the West and Syria and its key ally Russian Federation about the April 7 attack.
His remark follows Russian media reports saying Moscow is considering selling its sophisticated S-300 surface-to-air missile systems to Syria.
While weapons shipments into Syria are not uncommon, these flights involving Iran have caught the attention of U.S. intelligence because they occurred in the days after the April 13 USA airstrikes on Assad regime targets. All the aircraft were intercepted and captured by Russian troops by means of radio control.
Justin Bronk, an air combat expert at the Royal United Services Institute, said he doubted Russia's claims, and that the remarks were "probably just posturing in this case to try and embarrass the USA".

The official added that the government will introduce rules to regulate the use of recreational drones. Sunday's strikes are the latest in a series of rebel bombardments on Saudi territory.
In February, Israel shot down what it said was an armed Iranian drone that penetrated its airspace from Syria.
Russian Federation will supply Syria with new air defense systems, the RIA Novosti news agency said Wednesday, quoting General Sergei Rudskoy, chief of the Main Operations Directorate of the General Staff.
Immediately following the reports that Syria would be getting S-300s, Israel threatened to destroy the S- systems if Israeli warplanes are targeted.
If Israel attacks the new air defense systems, then it will suffer "catastrophic consequences", the officials said.
"There must be one clear thing - if someone shoots at our planes, we will destroy them", he added.
