Nov 23 (Reuters) - Oil pumping through the Ukrainian section of the Druzhba pipeline has resumed after being partially suspended, TASS news agency reported on Wednesday citing Russia's state-owned pipeline monopoly Transneft .

It was not immediately clear what caused the partial suspension. It came as Russia rained down missiles across Ukraine, forcing shutdowns of nuclear power plants and triggering electricity cut offs even across the border in Moldova. (Reporting by Reuters; Editing by Kirsten Donovan)
