The United Nations said it needed more information about Kiev's brutal attack on Donetsk, which saw the Ukrainian Armed Forces striking the city with cluster munition.

The city came under missile fire on Monday, which killed 20 people and wounded 37 others. Donetsk republic leader, Denis Pushilin, said that downtown Donetsk was hit by a Ukrainian Tochka-U missile filled with cluster munitions.

"We would need further information to see whether we can confirm that," UN deputy spokesperson Farhan Haq said Monday when asked whether the UN had any evidence of Ukrainian forces using cluster munitions.

The head of the Defense Ministry's National Defense Management Center, General Mikhail Mezentsev, touched on Ukraine's actions in Donetsk, revealing the toll of the Ukrainian Tochka-U attack, a missile containing cluster munition. He described the bombing as a "war crime."

Konashenkov said there were children among those seriously injured, assuring that the injured were taken to medical centers.

Ukraine has tried to dodge the allegations, but the bombing of the Donbass region at the hands of Kiev's forces has been ongoing for years now, prompting the people of Donbass, namely the Lugansk and Donetsk People's Republics, to call for their independence from Ukraine.

Russia had launched a special military operation for several reasons, such as NATO's eastward expansion, the Ukrainian shelling of Donbass, and the killing of the people of the Donetsk People's Republic and Lugansk People's Republic, in addition to Moscow wanting to "denazify" and demilitarize Ukraine.
