The European Union on Wednesday warned Russia and Ukraine that they face long-term consequences unless they immediately resolve a dispute that has cut gas supplies to Europe and left some countries struggling to heat up homes over the winter.
"If the transit (of Russian gas through Ukraine) does not go as normal, we will have a real problem", and the EU will have to conclude that "we no longer consider the supply of gas from Russia through Ukraine as credible," said European Commission President Jose Manuel Barroso.
