Russian forces continued offensive operations through Donetsk and Luhansk Oblasts, making limited gains.
The Head of the Luhansk Regional State Administration Serhiy Haidai stated that Russian forces in the area are focusing on securing territory from the direction of Bilohorivka, continuing attempts to seize Severodonetsk, and taking control of the highway to Lysychansk.
Meanwhile, the Ukrainian General Staff noted that Russian forces did not conduct active ground operations in Severodonetsk and instead heavily shelled Ukrainian positions in the Rubizhne-Severodonetsk-Lysychansk area.
This is consistent with ISW's previous assessment that Russian troops are likely increasingly unable to commit to a full-scale encirclement of the area east of the Izyum-Slovyansk-Debaltseve highway and are opting for a shallower encirclement with artillery support.
Ukrainian forces in the area are reportedly destroying Russian communications routes and railway bridges between Rubizhne and Severodonetsk to disrupt further Russian offensives on Severodonetsk and Lysychansk.
Meanwhile, Russian forces did not make any confirmed advances in any direction from Izyum on May 16 and focused instead on regrouping in preparation of renewed offensives, likely toward Slovyansk.
Ukrainian forces are continuing to mount attacks against Russian positions in the Izyum area, and the Ukrainian General Staff claimed that Ukrainian troops destroyed a Russian ammunition depot in Izyum on May 16.
Such targeted Ukrainian attacks are likely putting continued pressure on Russian logistical capabilities around Izyum and contributing to the disruption of any planned Russian offensives in this area.

Note: The Kremlin may have agreed to a conditional surrender of the Azovstal defenders to hasten its ability to declare full control of #Mariupol. It may also be seeking to deflect criticism of the failed Siverskyi Donets River crossings and the overall slow pace of the invasion.
The Kremlin might refuse to exchange the Mariupol defenders. Some Russian State Duma members are petitioning for laws that would prohibit prisoner exchanges for individuals accused of “Nazism." The Kremlin may ignore these concerns or use them to sabotage negotiations w/ Ukraine.
In any case, the surrender agreement generated some outrage and confusion on pro-Russian social media, rather than the celebration of the full capitulation of Mariupol that the Kremlin likely expected - possibly undermining Russian information operations. understandingwar.org/backgrounder/r…
Russian forces around Kharkiv City are notably trying to hold the border and prevent Ukrainian troops from advancing further north, as opposed to previous Russian withdrawals from around Kyiv, Chernihiv, and Sumy earlier in the war, which saw them pull completely back to Russia.
Russian troops may seek to retain positions in Ukraine and continue artillery strikes on Ukrainian positions in order to prevent Ukrainian forces from getting into tube or rocket-artillery range of the outskirts of Belgorod.
#Ukraine appears to have won the Battle of Kharkiv. Ukrainian forces prevented #Russian troops from encircling, let alone seizing Kharkiv, and then expelled them from around the city, as they did to Russian forces around Kyiv. 1/4 isw.pub/RusCampaignMay…
A Donetsk People’s Republic (DNR) serviceman said that the #Russian border patrol along the highway to #Belgorod refused to let his battalion, withdrawn from around Kharkiv City, into Russia for two days. 3/4 isw.pub/RusCampaignMay…
More highlights from our May 12 campaign assessment with @criticalthreats:
1. Continued and expanding reports of demoralization and refusals to fight among Russian units suggests the effective combat power of Russian troops in the east continues to be low and may drop further.
2. If the Russians abandon efforts to advance from Izyum, moreover, Ukrainian forces would be able to concentrate their efforts on defending Severodonetsk-Lysychansk or, in the worst case, breaking a Russian encirclement before those settlements fall.
3. The Ukrainian counteroffensive around Kharkiv is also forcing the Russian command to make hard choices. UK MoD reports that Russian forces pulled back from Kharkiv have been sent east, but at the cost of ceding ground from which the Russians had been shelling the city.
#Russian forces may be abandoning efforts at a wide encirclement of #Ukrainian troops along the Izyum-Slovyansk-Debaltseve line in favor of shallower encirclements of Severodonetsk and Lysychansk.
The relative success of Russian operations in this area combined with their failure to advance from Izyum and the notable decline in the energy of that attempted advance suggest that they may be giving up on the Izyum axis.
Reports that Russian forces in Popasna are advancing north, toward Severodonetsk-Lysychansk, rather than east toward the Slovyansk-Debaltseve highway, support this hypothesis.
As previously assessed, ISW believes Russian battalion tactical groups (BTGs) fighting in Ukraine have been so heavily degraded that counting them is no longer a useful metric of Russian combat power. @YahooNews: news.yahoo.com/russian-offens…
