Kherson ( Ukraine ) (AFP) - At least three people were killed Sunday by Russian shelling of residential areas in Kherson, southern Ukraine, local authorities said.

On the other hand, the authorities installed by Moscow in a Russian-controlled area in the neighboring region of Zaporizhia in the south of the country indicated that four people were killed in a Ukrainian strike on a railway bridge.

Recently, the front in southern Ukraine, where the Russian army was forced to abandon Kherson in November, has been calm compared to the front lines in the east of the country, where fierce fighting is taking place, but the shelling from both sides has not stopped, and fighting resumed this week in the Zaporizhia region.

"The enemy's artillery hit residential areas of the city," the Kherson regional administration said on social media.

It added that the bombing targeted a hospital, a school, a bus station, a post office, a bank and residential buildings.

These strikes left three dead and six wounded, including a nurse, according to the same source.

For his part, the head of the pro-Russian administration in Zaporizhia, Yevgeny Paletsky, accused the Ukrainian forces of launching "a strike with HIMARS missile launchers targeting a railway bridge spanning the Molochnaya River."

Paletsky added, "Four railway workers were killed, while five were injured while they were in the process of receiving treatment."

The bridge is located in a village north of the Russian-controlled city of Melitopol and is being repaired, according to the official.
