Addressing the members of parliament in Luxembourg via videoconference, Zelenskiy noted that the front line of the war expanded by about 1000 kilometers.
On the other hand, Russian forces intensified their attacks on the city of Severodonetsk in the Donbas region. The Russian army had hit a nitric acid depot inside a chemical plant in the city earlier this week.
British defense officials say that Russia has taken control of most of the city of Severodonetsk. Luhansk Governor Serhiy Haidai also announced that Russian troops took control of 70 percent of the city.
However, Haidai said Ukrainian troops counterattacked and “repulsed the enemy from many streets and took the soldiers hostage”.
It is also reported that the ongoing clashes in the city make it difficult for civilians to evacuate.
During the video conference, Zelenskiy also talked about the situation in Severodonetsk, where the fighting was intensifying. Zelenskiy stated that the situation in Donbas has not changed, but that the Ukrainians have made some partial gains in Severodonetsk.
It is estimated that there are 15,000 civilians in the city.
In occupied Mariupol, the former mayor of the city, Vadim Boychenko, accused Russian troops of executing officials who refused to cooperate with them.
Boychenko, who was released before the city came under Russian control, claimed that dozens of city residents were kept in prisons and torture reports were received. These claims could not be verified by the BBC.
Last week, an adviser to Boychenko told CNN that at least 22,000 people were killed during the Russian siege and bombardment.
