"We have submitted a new draft," the mission official stated.
The new draft resolution would request on-site investigations from the Organization for the Prohibition of Chemical Weapons (OPCW), Russia's Deputy UN Ambassador Vladimir Safronkov said.
"The Russian document does contain a clear request to do this [OPCW investigation] in a way to leave no doubt about the fact that in order to prepare its conclusions all possible sources and means have been exhausted and most importantly there has been a visit to the place where the incident took place," Safronkov stated.
Russia has repeatedly called for an independent investigation of the incident, which it says resulted from a Syrian government airstrike on a terrorist chemical weapons storehouse. Russia's UN envoy urged all parties to cooperate with any independent international investigation launched by the Organization for the Prohibition of Chemical Weapons.
Last week, Russia presented a draft resolution on the chemical attack in Syrian Idlib calling for a proper investigation into the incident.
