Germany has extradited a man from Russia's North Caucasus region back to Russia, where he faces allegations of taking part in terrorist activities in support of a banned Islamic extremist group.
Russia's Federal Security Service (FSB) did not name the man who was extradited on August 30, saying only that he was born in 1987 in Russia's Kabardino-Balkaria region.
The FSB said he was wanted for alleged assisting and supporting the banned Islamic group Imarat Kavkaz (Caucasus Emirate) in the North Caucasus and for fighting in Syria alongside militants from the Islamic State (IS) extremist group.
The FSB also said authorities suspect the man used false documents when he attempted to obtain refugee status in Germany.
According to Russia's government, some 2,000 Russian citizens are thought to have fought alongside IS militants in Syria. Most are from the North Caucasus region.
