Ukraine is said to be making “marginal advances” in the Kursk region as fighting continues, the Institute for the Study of War (ISW) has said.

We’ve brought you news on Ukraine’s struggles in the east of Ukraine (see 14.35 post) but further north, Kyiv’s incursion into Russia continues.

On 6 August, Ukraine threw a surprise counterpunch that saw their troops surge across the border into Russia.

Ukraine has previously claimed to have captured 1,250sq/km (480 square miles) and 92 settlements in Kursk, forcing tens of thousands to flee (see 12.53 post).

Today, Ukraine’s army chief said that its forces had advanced 28-35km (17-21 miles) into Kursk.

But the US-based thinktank said that, while still making progress, Ukraine was no longer eating up Russian territory as fast as it once was.

Using geolocated footage from 19 August, Ukrainian forces were confirmed to be in Vishnevka, the ISW said, around 14km (8.5 miles) from the border.

The Russian defence ministry said that they had struck forces operating in that area – potentially tacitly acknowledging the progress Kyiv had made.

It is known that Ukraine has targeted bridges in the region, perhaps as an effort to stifle Russian attempts to counter their incursion.

But Kyiv’s army chief said that Russia was moving troops from other directions to Kursk, to strengthen its positions there.

Even facing losses further east, Sky News’ military analyst Professor Michael Clarke said there were still opportunities from Kyiv in Kursk nonetheless (see 12.39 post).
