British Foreign Secretary Boris Johnson says that "all the evidence" he had seen so far in the latest chemical weapons attack in Syria "suggests this was the Assad regime who did it in the full knowledge that they were using illegal weapons in a barbaric attack on their own people."
Johnson also says that he does "not see how a government like that can continue to have any kind of legitimate administration over the people of Syria."
He added that he "would like to see those culpable pay a price for this."
Johnson spoke on Wednesday at the start of a Brussels pledging conference for Syria, where the United Nations, EU and world financial institutions have begun technical work to figure out what will be needed to rebuild war-ravaged Syria.
The Britain-based Syrian Observatory for Human Rights has said that at least 72 people died, including 11 children, in Tuesday's chemical weapons attack in a rebel-held town in northern Syria.
