Paris: Doctors Without Borders or Médecins Sans Frontières (MSF) said on Wednesday that its team had found victims showing symptoms consistent with toxins such as sarin gas after an attack in a rebel-held area of Syria that killed more than 70 people.
The team saw victims at the Bab al-Hawa hospital, 100 kilometres (62 miles) north of the attack on Tuesday, the charity said in a statement.
"Eight patients showed symptoms -- including constricted pupils, muscle spasms and involuntary defecation -- which are consistent with exposure to a neurotoxic agent such as sarin gas or similar compounds," the statement said.
The team also visited other hospitals where casualties were being treated "and reported that victims smelled of bleach, suggesting they had been exposed to chlorine".
Russia stood by its ally Syria on Wednesday ahead of a UN Security Council meeting to address accusations that President Bashar al-Assad's government had launched a chemical attack.
Moscow denounced a proposed UN resolution on the incident as "unacceptable". At least 72 people, including 20 children, were killed in the attack in Khan Sheikhun.
