U.S. National Security Adviser H.R. McMaster said on Saturday that public reports showed that Syrian President Bashar al-Assad was using chemical weapons and added that it was time for the international community to hold the government accountable.
"Public accounts and photos clearly show that Assad's chemical weapons use is continuing," McMaster said while speaking at the Munich Security Conference.
"It is time for all nations to hold the Syrian regime and its sponsors accountable for their actions and support the efforts of the Organization for the Prohibition of Chemical Weapons," he added.
