Russia launched a second major drone and missile bombardment of Ukraine in four days, officials said Tuesday, aiming again at the power grid amid freezing temperatures in an apparent snub to U.S.-led peace efforts as Moscow's invasion of its neighbor approaches the four-year mark.

These are the key developments from day 1,420 of Russia’s war on Ukraine. Here is where things stand on Wednesday, January 14: A Russian missile and drone attack on a postal company terminal in Ukraine’s northeastern city of Kharkiv killed four people and wounded six, Kharkiv Governor Oleh Syniehubov said on the Telegram messaging app.
