Ukraine has launched the rotation of troops on the frontline of the conflict with Russia, Oleksandr Syrsky, the commander-in-chief of the Ukrainian Armed Forces, said on Thursday, Paralel.Az reports citing Xinhua.

"Despite the rather difficult situation on the entire frontline, we managed to start the process of rotations and replacement of units and detachments that have been performing combat tasks at the front for a long time," Syrsky wrote on Facebook.

The rotation will help stabilize the situation on the battlefield and will have a positive effect on the moral and psychological state of Ukrainian soldiers, Syrsky said.

Later this month, the Ukrainian parliament is expected to vote on the bill tightening mobilization rules in the country.

Earlier, the Ukrainian authorities have voiced plans to mobilize between 450,000 and 500,000 people.
