An Arab League summit called on Sunday for an international probe into the "criminal" use of chemical weapons in Syria and condemned what it saw as Iran's interference in the affairs of other countries.
Saudi Arabia and Iran have for decades been locked in a struggle for regional supremacy that is now being played out in proxy wars in several countries, including Yemen and Syria.
"We stress our absolute condemnation of the use of chemical weapons against the Syrian people and we demand an independent international investigation to guarantee the application of international law against anyone proven to have used chemical weapons," said a statement distributed to journalists.
