Serbian President Aleksandar Vučić opened Friday Serbia’s 403 km extension of the Balkan Stream natural-gas pipeline, AP reports from Belgrade. Fuel for the line comes from Anapa, Russia, and then flow 930 km across the Black Sea in TurkStream. From northern Turkey, the line supplies Bulgaria, Romania and now, Serbia. It’s opening last year caused the sharp drop in Russian gas flowing across Ukraine. A Balkan Stream extension is planned to Hungary, currently a major importer of Russian gas through Ukraine. Last July, U.S. Secretary of State Mike Pompeo denounced TurkStream and Nord Stream 2 as “Kremlin tools.”
