Russia continues to slowly maneuver around Kyiv

 ISW:

Russian operations to continue the encirclement of and assault on Kyiv have likely begun, although on a smaller scale and in a more ad hoc manner than ISW expected. The equivalent of a Russian reinforced brigade reportedly tried to advance toward Kyiv through its western outskirts and made little progress. Smaller operations continued slowly to consolidate and gradually to extend the encirclement to the southwest of the capital. Russian operations in the eastern approaches to Kyiv remain in a lull, likely because the Russians are focusing on securing the long lines of communication running to those outskirts from Russian bases around Sumy and Chernihiv in the face of skillful and determined Ukrainian harassment of those lines. The battle for Kyiv is likely to continue to be a drawn-out affair unless the Russians can launch a more concentrated and coherent attack than they have yet shown the ability to conduct.

The Russian military is clearly struggling to mobilize reserve manpower to offset losses and fill out new units. The Kremlin admitted that conscripts have been fighting in Ukraine (in violation of Russian law) for the first time on March 9, although in a customarily bizarre fashion: according to the Kremlin, Vladimir Putin himself discovered that conscripts were operating in Ukraine while he was reviewing a report on the conflict. The Kremlin says Russian military judicial authorities will reportedly open an investigation into this practice and punish those responsible.[1] Putin himself would, of course, ultimately be responsible for having issued the mobilization orders that sent conscripts to the front. Reports have also surfaced that students at medical and theater schools were being conscripted in late February, along with some denials of those reports.[2] Social media users also flagged the movement of Russian peacekeeping forces in the Nagorno-Karabakh region, speculating that they may be withdrawing to participate in the war in Ukraine.[3] ISW cannot independently verify any of these reports. Their general tenor, however, aligns with our published assessment that Russia faces challenges in generating a new wave of combat-effective reservists or recruits in a short period of time and our assessment that Russia will need such a wave to complete its objectives.[4]

This report seems to confirm that Russia has suffered significant casualties even before it attacks Ukraine's main defenses in the cities.  ISW also thinks Russia may create a false flag operation using chemical or radiological material as a reason for escalating the conflict.  The Russians do not seem able to use large-scale operations at this point. I get the impression that Ukraine forces are still capable of inflicting significant casualties on the Russian forces and that has continued to slow their advance.
