Medical staff and aid workers are reporting on the incident in Douma, the last rebel-held town in Syria's Eastern Ghouta.
The White Helmets group claimed civilians had been targeted by 'poison gas.'
Apparent photos of victims online show foaming from the mouth.
The Syrian government is being blamed for the alleged attack, however they have denied being behind it.
The US State Department's strongly condemned the incident, and they have called on Russia to end its support for the Assad regime.
