A Russian strike in eastern Ukraine on Friday killed three people on a bus near the embattled town of Kupiansk, which Moscow's army is battling to recapture, investigators said.
The wider Kharkiv region, which borders Russia, was partly occupied when Russian forces invaded in February 2022, but was largely liberated by Ukraine months later.
"Three people were killed as a result of the strike: the bus driver and two passengers," local investigators announced.
The bus was near the village of Nova Oleksandrivka when it was hit by an Iskandr missile, they added. Investigators posted images of a red bus with its windows blown out.
There was no immediate comment from the Kremlin, which claims its forces do not target civilians.
Peace talks spearheaded by the United States aiming to halt more than four years of fighting have been derailed by the US-Israeli war with Iran.
Russia's invasion sparked the bloodiest war in Europe since World War II, forcing the displacement of millions and leaving hundreds of thousands of soldiers and civilians dead on both sides.
