Authorities are targeting illegal activity that could involve up to $6 billion....
The preliminary investigations for the co-ordinated operation were undertaken jointly by inspectors from the Finance Ministry, the Ankara State Security Court and the Turkish police.
The investigations will look at the issue of corruption in Turkey on a wider scale, with some authorities saying they would cover all illegal action from phantom exports to drugs smuggling.
Sources say that some 700 large and small scale companies were involved in phantom export, drugs, money laundering and having links to criminal gangs. This figure could rise as investigations are expanded.
