Chechen President Ramzan Kadyrov believes the mysterious leader of the self-proclaimed Islamic State and former Camp Bucca inmate Abu Bakr al-Baghdadi is a CIA operative.

"Baghdadi should take off his mask and declare loudly and clearly that he is a CIA agent, that he has been recruited," Kadyrov said. "They (the Islamic State) are Shaitans (devils) and their sole obsession is to grab as much money as they can lay hands on. They are acting on orders from the West and deliberately exterminating Muslims."

"He must openly confess that he is killing his brothers in faith, to apologize to his coreligionists and to disband his gang," Kadyrov said.

Kadyrov has a checkered past and stands accused of corruption and human rights violations. He has cooperated with Russia's FSB state security service since the Second Chechen War in 1999 when he led the Kadyrovite militia. His father, former Chechen President Akhmad Kadyrov, launched a jihad against Russia. He was assassinated in 2004.
