Ukrainian President Volodymyr Zelensky says that investigators have uncovered more than 400 war crimes in areas of Kherson abandoned by Russian forces as they retreated, BBC report.

Ukrainian President said the bodies of civilians and soldiers had been found.

The BBC has been unable to verify the allegations. Moscow denies its troops intentionally target civilians.

Meanwhile Ukrainian authorities imposed an overnight curfew and restricted travel in and out of Kherson.

“In the Kherson region, the Russian army left behind the same atrocities as in other regions of our country, where it was able to enter,” Mr Zelensky said in his nightly video address.

“We will find and bring to justice every murderer. Without a doubt.”

Since the start of the war, mass graves have been found in areas including Bucha, Izyum and Mariupol. Ukraine has accused Russian troops of being behind the atrocities.

A UN commission last month said that war crimes had been committed in Ukraine and that Russian forces were responsible for the “vast majority” of human rights violations at the start of the invasion.
