Officials report 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.
Pokrovsk is located around 70 kilometres (43 miles) north-west of the Russian-occupied city of Donetsk. It had a population of about 60,000 before the war.
The leader of the Donetsk region, Pavlo Krylenko, said that a member of the emergency services was killed in the second strike and that five people were murdered in the first strike. Additionally, a military employee perished.
He said, “High-rise buildings, private houses, administrative buildings, catering establishments, [and] a hotel” were among the “destroyed and damaged” structures.
“Russia is a state that sponsors terrorism. And she ought to pay for her sins!” he continued in a Telegram post.
Other Ukrainian officials claim that the second missile, which landed 40 minutes after the first, killed and injured rescuers who were looking for survivors in the rubble of what Mr Zelensky called a “ordinary residential building,” killing and injuring them in the process.
He released a video showing the top floor of a five-story building being destroyed.
It showed individuals helping one another into ambulances and clearing away debris amidst scenes of general mayhem and uncertainty.
A local who was hurt in the initial strike, Kateryna, told the news agency Reuters that she was at home when the missile struck.
“My eyes were filled with flame. I stumbled and hit the ground and floor. Only the shrapnel in my neck is hurting me; otherwise, I’m fine.
At least two civilians were also killed, according to Andriy Yermak, chief of the Ukrainian Presidential Office, when Russian guided bombs struck “private houses” in the Kharkiv Region on Monday night.
He said that five persons were hurt in the attacks.
