Britain and France on Tuesday (August 30th) called for UN sanctions to be imposed on Syria after a UN-led investigation found the regime had carried out chemical attacks, AFP reported.

The UN ambassadors from London and Paris described the use of chemical weapons against civilians as a war crime, ahead of a closed-door council meeting to discuss the investigation's findings.

French Ambassador Francois Delattre called for a "quick and strong Security Council response" that would include "imposing sanctions on those who are responsible for these acts".

An investigative panel set up by the Security Council said in a report last week that regime forces had carried out at least two chemical attacks, one in 2014 and one in 2015.

British Ambassador Matthew Rycroft said the council will be "looking at the imposition of sanctions and some form of accountability within international legal mechanisms" and called for a "robust international response".

Syrian Ambassador Bashar Jaafari on Tuesday rejected the investigation's findings, while Russian Ambassador Vitaly Churkin said Russia has "very serious questions" and was not yet prepared to accept the investigation's findings.
