Syria attack symptoms consistent with nerve agent use, says WHO

The World Health Organisation (WHO) on Wednesday said victims of a suspected chemical attack in Syria appeared to show symptoms consistent with reaction to a nerve agent.

“Some cases appear to show additional signs consistent with exposure to “organophosphorus” chemicals, a category of chemicals that includes nerve agents,” WHO said in a statement.

WHO has put the death toll at no fewer than 70.

The U.S. has said the deaths were caused by sarin nerve gas dropped by Syrian aircraft.

Sarin is an“ organophosporus” compound and a nerve agent.

WHO added that chlorine and mustard gas, which are also believed to have been used in the past in Syria, are not.

Russia has said it believes poison gas had leaked from a rebel chemical weapons depot struck by Syrian bombs.

A Russian Defence Ministry spokesman did not say which agent was used in the attack but said the rebels had used the same chemical weapons in Aleppo in 2016.

The WHO said it was likely that some kind of chemical was used in the attack because sufferers had no apparent external injuries and died from a rapid onset of similar symptoms, including acute respiratory distress.

It said its experts in Turkey were giving guidance to overwhelmed health workers in Idlib on the diagnosis and treatment of patients.

It added that medicines such as Atropine, an antidote for some types of chemical exposure and steroids for symptomatic treatment had been sent.

UN Commission of Inquiry into human rights in Syria has previously said forces loyal to Syrian President Bashar al-Assad have used lethal chlorine gas on multiple occasions.

Hundreds of civilians died in a sarin gas attack in Ghouta on the outskirts of Damascus in August 2013.

Meanwhile, Assad’s government has always denied responsibility for that attack.

Syria agreed to destroy its chemical weapons in 2013 under a deal brokered by Moscow and Washington.

However, Russia, a Syrian ally and China have repeatedly vetoed any UN move to sanction Assad or refer the situation in Syria to the International Criminal Court.

Peter Salama, Executive Director of the WHO Health Emergencies Programme, said in the statement that those types of weapons were banned by international law because they represented an intolerable barbarism.
