However, it was announced that the civilians leaving Severodonetsk could only go to the Russian-occupied areas.
Crossings between Severerodonetsk and other parts of Ukraine became nearly impossible as the Russian army blew up key bridges in the city.
Ukrainian forces say they are making efforts to evacuate civilians, even though the bridges have been destroyed.
It is thought that about 12,000 civilians remain in Severodonetsk. The city, located in the separatist Luhansk region in eastern Ukraine, had 100 thousand people before the clashes started.
It is stated that the Russian army has announced that it will allow the Ukrainian soldiers trapped in the Azot chemical facility to surrender, provided that they lay down their weapons.
On the other hand, the Ukrainian army announced that they successfully defended their positions in Severodonetsk and Toshivka against Russian forces.
It is stated that the Russian army carried out attacks on the main city centers of Severodonetsk with mortars, artillery fire and multiple rocket systems.
President of Ukraine Volodymyr Zelenskiy said that the defense of the Donbas region in the east of the country is of vital importance and that the course of the war will be determined by what happens in this region.
Zelensky also repeated that Ukraine needs modern anti-rocket weapons.
Defense ministers of NATO member states are expected to meet in Brussels today to discuss increasing arms supplies to Ukraine.
