German investigators say they have shut down a Russian-language darknet marketplace that specialised in drug dealing.
Prosecutors in Frankfurt described the "Hydra Market" platform as the world's largest illegal marketplace.
They said they seized its server infrastructure in Germany as well as bitcoin cryptocurrencies worth €23 million.
The operation was the result of international investigations since August 2021, prosecutors said.
"Hydra Market" -- active since at least 2015 -- was used to sell illegal drugs, forged documents, intercepted data and "digital services".
