KYIV, Dec 23 - Russia attacked Kyiv and Ukraine’s energy infrastructure early on Tuesday, triggering emergency outages and prompting NATO member Poland to scramble jets to protect its airspace, two days after U.S.-led Miami peace talks ended.

The weekend peace talks in Miami brought together U.S. officials with Ukrainian and European delegations, alongside separate contacts with Russian representatives, as Washington tested whether there was scope for a settlement to end Russia's war in Ukraine.
