Rosneft, Russia's biggest oil producer, on Sunday slammed European Union sanctions on India's Nayara Energy refinery as unjustified and illegal, saying the restrictions directly threatened India's energy security.

The EU also targeted the Nord Stream pipelines between Russia and Germany to prevent Putin from generating any revenue from them in future, notably by discouraging would-be investors. Russian energy giant Rosneft’s refinery in India was hit as well.

The European Union agreed to block attempts to revive the Nord Stream gas pipelines and lower a price cap for Russian oil sales, among other measures.
