Russian Foreign Minister Sergey Lavrov said on Tuesday that it is too early to talk about mediation in talks with Ukraine, though Russia remains committed to a diplomatic solution, reported Reuters. 

His comments come after Russian President Vladimir Putin last week accused Ukraine of not being ready to seek mutually acceptable solutions.

An FT report this morning suggested that the EU is mulling a cap on the price paid for Russian oil as a way to hit Kremlin revenues in its next sanctions package.
