BERLIN, Oct 9 - An external power line to Ukraine’s Zaporizhzhia nuclear power plant — the biggest in Europe — was repaired on Sunday after shelling disconnected the facility from the grid and forced it to resort to emergency diesel generators, the U.N. nuclear watchdog said.

The International Atomic Energy Agency said the 750-kilovolt line was reconnected to the plant on Sunday evening following repair work by Ukrainian engineers, The Associated Press reported. That enabled the plant to start switching off the generators that had kicked in to provide it with power after the line — its last connection to the grid — was cut early Saturday.
