The journalist Patrick Cockburn has been covering events in the Middle East since the 1970s, and he's pointing out how difficult it is to determine who was responsible for the latest war crime in Syria:

"PATRICK COCKBURN: Well, there's reporting from within Douma, which at that moment was held by Jaysh al-Islam, but the hospital that we saw shots of now seems to be held by the Syrian army. And there were film of dead and dying children, there was shots of gas cylinders.
"The problem with this is that all this comes from the people inside Douma, which as you said is controlled by Jaysh al-Islam.
"There's been no independent verification yet.
"And it's pretty clear from what, for instance, in Britain Theresa May is saying, that we are still waiting to be sure who carried out this attack.
"That governments are being told by their own intelligence services that it's not exactly clear what happened.
"Curiously, the media reporting this sounds much more sure in attributing blame to the Assad government than the people like Theresa May and other political leaders who presumably are getting other information from their intelligence people."
