Over in Kursk, Russia kicked off the second phase of its counteroffensive, after the first one stalled around Liubimovka and Sverdlikovo, and with the Ukrainian diversionary attack towards Veseloe. Multiple small motorised and mechanised groups rushed deep into Ukrainian lines, both along the main Korenevo-Sudzha road, as well as toward Liubimovka and Olgovka. Ukrainian troops were caught off guard, and were unable to halt this rapid assaults, such as with this Ukrainian tank being chased by 2 Russian BTRs. This video actually takes play far to the south east of the advance shown here, at the end of the longest red arrow (under the y).
Whilst information and reports are scattered, what could be confirmed is that Russian troops were able to recapture Matveeka (red dot above S) and Olgovka (red dot above u), as well as a large portion of the fields in that area. Suriyak is being conservative with the rest of this area, at least until we get further confirmation, but Ukrainian troops have likely quickly retreated from the large forest area near Olgovka, as well as from most of the fields near the main road until Zelenyi Shylakh (blue dot below y), pulling back to friendly positions around the villages.
Now to burst the bubble of those who have read a particular claim, no, Ukrainian troops haven’t started to abandon Kursk and flee in large columns. That rumour seems to have been started by a random Telegram channel, but quickly denied by other Russian sources. Ukraine is reported to be gearing up for a counterattack, or at least trying to reinforce these areas, but the actual situation and control is unclear for much of this area. What can be said is that if Ukraine do not respond quickly, they are likely to lose many of these villages and positions, and thus most of the north of the front. This would put Sudzha at risk of an attack from the northwest, as well as threaten the entire Ukrainian Kursk grouping (pic below).
At the same time as the above, there was a separate Russian advance towards Novaya Sorochina, on the northeast side of the front. Russian MoD claimed they had recaptured this settlement, however only the advance up to and including the railway could be confirmed. The village currently sits in the greyzone, at least until there is clarification as to whether Russian troops did in fact enter the settlement.
