Bulgaria may build an 80-kilometer (50-mile) natural gas pipeline between its southern city of Haskovo and Komotini in northern Greece. The link would be joined to an existing pipeline between Turkey and Greece and carry natural gas from Iran or Azerbaijan to Bulgaria’s southern regions along the Greek border, Bulgaria’s Economy and Energy Minister Petar Dimitrov said in Sofia yesterday. Bulgaria would negotiate additional gas supplies with Iran and Azerbaijan should the project be implemented, Dimitrov said. The Balkan country signed a contract with Russia’s OAO Gazprom until 2030, as well as an accord for the South Stream pipeline, a link that stretches from Russia to the European Union via the Black Sea.
