Russia launched another massive drone and missile attack on Ukraine overnight, launching nearly 300 drones, as well as 18 ballistic missiles and seven cruise missiles. The attack targeted Ukraine’s power infrastructure, leaving thousands more without heat. Four people were killed in Kharkiv.

Meanwhile, a U.N. monitoring group says about 2,500 Ukrainian civilians were killed last year, making it the deadliest year yet for civilians since Russia’s full-scale invasion in 2022.
