In a classic Putin move, the Russian President presented evidence of G20 member states providing financial support to ISIS…during the G20 summit in Antalya. Speaking with reporters after the summit, Putin revealed: 

I provided examples related to our data on the financing of Islamic State units by natural persons in various countries. The financing comes from 40 countries, as we established, including some G20 members

Putin also provided satellite images of the Islamic State's lucrative oil smuggling operations: 

I've demonstrated the pictures from space to our colleagues, which clearly show the true size of the illegal trade of oil and petroleum products market. Car convoys stretching for dozens of kilometers, going beyond the horizon when seen from a height of four-five thousand meters

Interestingly, immediately after the summit, the U.S. announced that its warplanes had begun to bomb ISIS truck convoys  used to “smuggle the crude oil it has been producing in Syria”. What a strange coincidence. It's as if the U.S. knew exactly where these convoys were, but didn't feel compelled to destroy them until now. The world is full of mysteries! 

But the real story here is that Putin actually got up in front of the world's largest economic powers and told them, right to their faces, that Russia knows exactly what they are doing. 

Respect.
