"Saudi Arabia is not a terrorist organization but it is a country which… finances terrorist formations, and despite this, this country is an ally of the United States and Europe, so unfortunately the fight against terrorism at this moment is not a united fight," Wagenknecht said in a documentary that was broadcast Sunday, on the Rossiya 1 television channel.
Last week, Saudi Arabia announced the creation of an Islamic military alliance of 34 states to fight terrorism. The joint operation command center will be based in the Saudi capital of Riyadh.
Saudi Arabia is also a member of a US-led coalition of over 60 countries that has been conducting airstrikes against the Islamic State (ISIL or Daesh) militant group in Iraq and Syria since September 2014, without the approval of the Syrian government or the UN Security Council.
Russia has been carrying out precision airstrikes against Daesh, having outlawed it, in Syria since September 30, at the request of Syrian President Bashar Assad.
