KYIV (Reuters) - Russia and Ukraine accused each other on Friday of shelling Europe's biggest nuclear power plant as fighting raged again in the crucial border region of the Donbas and three more ships left ports carrying previously blockaded Ukrainian grain.

Shells hit a high-voltage power line at the Zaporizhzhia plant, prompting operators to disconnect a reactor despite no radioactive leak being detected. The plant was captured by Russian forces in early March in the opening stage of the war but it is still run by its Ukrainian technicians.
