According to Kupchishin, the fighters from the illegal militant groups continue to destabilize the situation in the Idlib de-escalation zone.
"According to information received by the Reconciliation centre, a group of foreign media resources' correspondents conducted a staged filming of the death of a Syrian family from chemical weapons allegedly used by the Syrian government troops in the area of Morek in the Hama province," Kupchishin said.
He also noted that the Russian Centre for Syrian Reconciliation urges leaders of the illegal militant groups to stop provocations and join the efforts in dealing with the situation by peaceful means in territories where they are operating.

In late March, Russia's Permanent Representative to the UN Vasily Nebenzya reportedly said that militants and the White Helmets were preparing new staged chemical attacks in Syria's Idlib.
Moscow and Damascus have on a multitude of occasions pointed out that the White Helmets have staged a number of provocations in Syria involving the use of chemical weapons in order to blame them on the Syrian government and provide Western countries with justification for intervention in the Arab Republic.
Kupchishin argued at the time that Belgian special services had been filming strikes by Russian Aerospace Forces on terrorist arms depots in order to use that footage to accuse Russia of using of chemical weapons.
Syria was plunged in a military conflict in 2011. Victory over the Daesh terrorist group was declared in late 2017, and the political settlement as well as the return of refugees and rebuilding have come to the forefront since then.

The Idlib de-escalation zone now remains the last major stronghold of terrorists and armed rebels in Syria. In September 2018, ceasefire guarantors Russia and Turkey agreed to set up a 9 to 12-mile deep demilitarized zone in the province, which would be cleared of heavy weapons and militants.
However, despite progress in the withdrawal of weapons and fighters from the area, remaining militants regularly commit ceasefire violations by shelling nearby provinces.
