Kremlin spy suspect arrests may be tip of iceberg, says former German agency chief

Gerhard Schindler says Russia has been ‘ramping up’ operations in west, as two men are accused of plotting sabotage at military sites

A former head of Germany’s foreign intelligence service has warned that the discovery of two men suspected of plotting sabotage attacks on military facilities in the country could be just the “tip of the iceberg”.

After the arrest of the Russian-German citizens Dieter S and Alexander J on Wednesday, who are alleged to have been operating as spies on behalf of the Kremlin, Gerhard Schindler, the former chief of the BND, the equivalent of MI6, said it would be naive to see the incident as an isolated one.
