BERLIN (Reuters) - The suspect detained over the killing last week of a Georgian citizen in Berlin had a passport whose number linked him to Russian security services, German magazine Der Spiegel reported on Friday.
Zelimkhan Khangoshvili, who had previously fought alongside anti-Moscow separatists in the province of Chechnya, was shot twice in the head last Friday as he headed through a central Berlin park to the mosque.
Spiegel said an investigation conducted jointly with the investigative networks Bellingcat and The Insider had found that nobody with the name of the alleged assassin was to be found in the Russian national passport register.
It added that his passport number was associated with an interior ministry unit that had in the past issued identity documents for agents of the GRU military intelligence service.
