Claim: Zurab Khangoshvili was one of the organizers of explosions in the Moscow metro.

Q1: Who is Zurab Khangoshvili?
A1: Khangoshvili served as a field commander in the second Chechen war with Russia (August 1999-April 2009) and as an intermediary between Georgian security services and the Chechens. More recently, he helped organize resistance in the Russia-occupied territories of Ukraine. Following several assassination attempts, Khangoshvili sought asylum in Germany with his family.

Q2: What happened to him?
A2: Zelimkhan Khangoshvili, 40, an ethnic Chechen from Georgia, was killed in Berlin on Aug. 24 in a broad daylight. Witnesses told police the killer rode up on a bicycle, shot Khangoshvili twice and pedaled away. The suspect was captured after being seen dumping a wig, handgun and his bicycle in the Spree River.

Q3: Why was he killed?
A3: The Berlin general prosecutor said the murder was a professional operation. According to Western media reports, German prosecutors suspect it was a state-sponsored contract killing. Russian officials have strongly denied any connection.

Q4: Was Zelimkhan Khangoshvili a wanted man in Russia and one of the organizers of explosions in the Moscow metro?
A4: Putin’s assertion that Zelimkhan Khangoshvili, was “wanted” in Russia could not be verified. As Polygraph.info previously reported, neither the name Zelimkhan Khangoshvili, nor his adopted name Tornike Kavtarashvili, are on the official list of terrorist suspects wanted in Russia. If Russia is seeking his extradition for terrorism, details have not been disclosed.
