Ukrainian energy adviser Bohdan Sokolovsky Presedential Press Service A top Ukrainian official says Russia is trying hard to discredit Ukraine by sending natural gas intended for Europe on a technically impossible transit route over Ukraine's vast pipeline system.

Ukrainian energy adviser Bohdan Sokolovsky says Russia has shipped natural gas along a route that would require Ukraine to cut domestic consumers out before it can deliver gas to the Balkans.

Russia's Gazprom state-controlled gas monopoly resumed shipments to Europe via Ukraine on Tuesday, but then accused Ukraine of blocking the transit of gas.

Sokolovsky said a gas entry point on the Russian border and a gas pumping station near the Romanian border where Gazprom wants its gas delivered are not linked by an export pipeline.
