WASHINGTON: The White House on Saturday condemned the Syrian regime of al-Assad as ‘defiance’ of international norms after United Nations experts found its army had conducted three chemical weapons attacks against its own people in 2014 and 2015. Of the nine alleged chemical attacks being investigation, the UN-led team attributed three to the Syrian government and one to the Islamic State (IS) militants. “We strongly urge all UN member states and parties to the Chemical Weapons Convention, including Russia and Iran – which continue to conduct military operations on behalf of the Assad’s regime – to support and sustain the shared international commitment against the use of chemical weapons,” the White House said.
