British Prime Minister Theresa May says the Syrian regime "and its backers, including Russia, must be held to account" if the government is found to be responsible for a suspected poison gas attack in the country.
May says those who back "the brutal actions by (Syrian President Bashar) Assad and his regime ... they need to look very carefully at the position they have taken." She calls Saturday's suspected attack on the besieged town of Douma "a reprehensible attack," adding Britain is in talks with its allies about "what action is necessary."
