Roger Waters denounced the White Helmets, a Syrian volunteer group and a 2017 Nobel Peace Prize nominee, during a concert last Friday in Barcelona, calling them a "fake organization" that prompted propaganda for "jihadists and terrorists".
"I believe the organization that he purports to represents and who he supports - the White Helmets - are a fake organization that exists only to create propaganda for the jihadists and terrorists", said Waters, who in recent years has become known for his vocal backing of a boycott of Israel. "This would be a mistake of monumental proportions for us as human beings", he said.
Many took to social media to praise Mr. Waters for lifting the White Helmet's façade and exposing the group.
The former Pink Floyd frontman claimed that listening to "propaganda of the White Helmets and others we would be encouraged to encourage our governments to go and start dropping bombs on people in Syria", in a video posted on YouTube by a group called Hands off Syria.
"What we should do is go and persuade our governments not to go and drop bombs on people. Because we live in the world where propaganda seems to be more important than the reality of what is really going on".
Mr. Waters is one of many who have been very vocal in their opposition to the strikes against Syria by the US, France and the United Kingdom, which were supposedly carried out in retaliation to an alleged chemical attack in the city of Douma earlier this month.
Chemical weapons attacks have killed thousands of people since the start of Syria's conflict, with the United Nations blaming four attacks on the Syrian regime and a fifth on the Islamic State group.
