At least four people were killed in a Russian drone attack in Brovary district near Ukraine's capital Kiev, the Kiev regional governor Mykola Kalashnyk said on Telegram.

Seven others were injured, Kalashnyk said. Russia attacked a food industry company, and the casualties were employees, he said. Parts of the building were destroyed and a fire broke out. Up to two more people could still be under the rubble, he said.

Ukraine has been defending itself against Russia's invasion with Western military and financial help for more than four years.
