Deadly air strikes hit residential buildings in Ukraine and the Russian border region on January 2, 2024, in an escalation of aerial attacks that killed five people and 130 wounded, less than 24 hours after Russian President Vladimir Putin vowed to step up strikes following an unprecedented Ukrainian attack on the Russian city of Belgorod.
