(ANSA-AFP) - ANKARA, SEP 6 - Turkish President Recep Tayyip Erdogan on Tuesday blamed Europe's energy crisis on sanctions it imposed on Russia over the invasion of Ukraine -- a line taken by the Kremlin itself. Erdogan has maintained good working relations with Russian President Vladimir Putin while trying to stay neutral in the conflict and supplying Ukraine with Turkish weapons and combat drones. He told reporters before departing for a three-nation swing through the Balkans that European nations were "harvesting what they sowed" by imposing economic restrictions on Russia. "Europe's attitude towards Mr Putin, its sanctions, brought Mr Putin -- willingly or not -- to the point of saying: 'If you do this, I will do that,'" Erdogan said. "He is using all his means and weapons. Natural gas, unfortunately, is one of them." Erdogan's comments echo those expressed by the Kremlin this week. Kremlin spokesman Dmitry Peskov on Monday blamed Russia's halt of gas deliveries to Germany via the Nord Stream pipeline on "sanctions that were imposed against our country". Russia accounted for nearly half of Turkey's own natural gas purchases last year. (ANSA-AFP).
