KYIV, Jan 7 - U.S. and Ukrainian negotiators will revisit the thorny issues of territory and the fate of the occupied Zaporizhzhia nuclear power plant, President Volodymyr Zelenskiy said on Wednesday, the most problematic points in peace talks to end Russia's war.

Kyiv is under U.S. pressure to secure peace in the nearly four-year-old conflict but is pushing back on Russian demands to cede its eastern Donetsk region and give up control of Europe's largest nuclear facility.
