Officials report states that a Russian missile attack on homes in the eastern Ukrainian town of Pokrovsk has resulted in at least seven fatalities.
As rescuers were looking for victims of the first rocket, two missiles struck the town.
Police officers and rescuers were among the numerous injured. Over 30 individuals, including two children, were injured.
Rescue efforts are still going on.
About 70 kilometers (43 miles) north-west of the Russian-occupied city of Donetsk sits Pokrovsk. There were about 60,000 people living there prior to the conflict.
Five civilians were murdered in the first strike, according to the leader of the Donetsk region, Pavlo Krylenko, and a member of the emergency services was killed in the second strike.
He added that the buildings which were “destroyed and damaged” were “high-rise buildings, private houses, administrative buildings, catering establishments [and] a hotel”.
“Russia is a terrorist state. And she must be punished for her crimes!” he added in a post on Telegram.
According to other Ukrainian officials, the second missile struck 40 minutes after the first, killing and wounding rescuers as they searched for survivors in the ruins of what Mr Zelensky described as an “ordinary residential building”.
