The reporting of Dilyana Gaytandzhieva immediately comes to mind as she helped expose the illegal weapons smuggling operation from Eastern European nations like Bulgaria, Serbia and Belarus where soviet weapons were procured by US contractors and shipped under diplomatic cover to conflict zones in the Middle East, including Syria. Arms were shipped using diplomatic immunity provided by Azerbaijani government for Silkway Airlines (a commercial airliner).
This report bolsters Dilyana's expose and shows that she was wrongfully fired from her job for uncovering the truth behind the massive weapons smuggling operation.
Here's Dilyana's original report from July 2017 and I also created a 6 part series based on her reporting and the powerful documentation provided by anon_bg.

I reached out to her for an interview! Hopefully she responds!
