But it can also be the case that they want to withdraw to get a break before they attack the capital again with even greater force, Sundström says.

He believes that this is a military strategic move on the part of Russia.

Russia has announced several times before that it intends to concentrate its military attacks on eastern Ukraine in the future.

- If you do not invest so hard in Kyiv in the next few days or weeks, then you get more strength to beat Ukrainian forces in that area and it strengthens Russia in the long run, says Bert Sundström.
