Speaking at the party’s annual congress, Ozdemir urged Germany to re-examine its relations with Saudi Arabia; he said arms are shipped to the country and oil returns, according to the Iranian news network Press TV.
Ozdemir said that speaking of the destruction of ISIL Takfiri terrorists is irrelevant as long as this hypocrisy remains.
"Saudi Wahhabism is not part of the problem. It is the source of the problem," he pointed out.
He made the remarks despite Saudi Arabia's alleged sponsorship of terrorist groups in Syria, its continued use of public execution as a tool of political repression, and its military role in neighboring Yemen, none of which has stopped the West from selling arms to Saudis.
Earlier this month, it was reported that the US State Department had approved a 1.29-billion-dollar sale of smart bombs to Riyadh.
As for Takfirism, it is thought to be largely influenced by Wahhabism, the radical ideology dominating Saudi Arabia and freely preached by the country's clerics.
