Syria chemical attack: 'Many children have been killed'

The US is calling for an international response against the Syrian government if reports of a chemical attack on a rebel-held area of Eastern Ghouta are confirmed.

Medics say about 70 people were killed in the suspected gas attack in Douma.

The Syrian government is calling it a fabrication.

Rescuers say they are struggling to get to the survivors and retrieve the bodies of the dead because of a strong chlorine-like smell.

They do not have the protective gear they need and the healthcare system in Douma has been devastated by the long government siege. Al Jazeera's Natasha Ghoneim reports from neighbouring Jordan.
