Six postal workers were killed and 16 more were hurt when a missile struck a distribution center in eastern Ukraine late on Saturday night.
The Ukrainian President, Volodymyr Zelensky, reported on Telegram that the Nova Poshta sorting office in Kharkiv was hit.
The photos on President Zelensky’s account showed a building with broken windows.
The governor of Kharkiv, Oleh Syniehubov, said that all the people who were hurt worked for the postal company.
The police said there were 22 people inside a building when a suspected S-300 rocket hit it right before 10:30 PM local time (8:30 PM BST).
Investigators, along with crime experts and scientists, are looking at the bodies of the deceased, the police said on social media.
Mr Syniehubov wrote on Telegram that the people who got hurt were between 19 and 42 years old. Some of them had wounds caused by flying pieces from the explosion.
He said that the delivery company in the western Kharkiv suburb of Korotych was only for regular citizens and not for any military purposes.
He said that the Russians have caused more fear and violence among the calm people in Kharkiv.
President Zelensky said that they are still trying to rescue people and emergency services are working at the place where the incident happened.
Russia has not said anything about the reported attack yet. But they have said before that they did not intentionally harm innocent people when they went into Ukraine.
Mr Syniehubov mentioned that there were seven people in the hospital who were not too sick and seven men who were very sick.
Kharkiv is a big city in Ukraine, and it is not too far from Russia.
The city in the northeast was badly attacked with bombs in the early weeks of the war in February 2022.
Earlier this month, the Mayor of Kharkiv, Ihor Terekhov, announced that a new school will be built underground in Ukraine. This unique school will provide a safe environment for children to attend classes in person.
At the same time in the southern part, Ukraine has been fighting back since June.
The country that has been badly affected by war wants to cut off the land connection Russia has to the Crimean peninsula, which Russia took over unlawfully in 2014.
However, the counter-attack has been progressing slowly and has only resulted in small amounts of land being reclaimed.
