Ukraine has continued its offensive actions across its salient of control on Russian soil, according to the US-based Institute for the Study of War (ISW).

Geolocated footage showed Russian forces striking a Ukrainian armoured vehicle in Martynovka, a village southeast of Ukrainian-controlled Sudzha. The ISW said the footage indicated “that Ukrainian forces recently advanced into northern Martynovka”.

The Kyiv-based Centre for Defence Strategies said that Ukraine’s 103rd Territorial Defence Brigade had captured the village of Vnezapnoye and encircled Russian FSB border guards near Glushkovo.

The think tank wrote that Ukrainian forces had taken control of Tolpyno and Kolychevka, cutting off the Russian garrison in Korenevo from the main enemy forces, in an overnight assessment of the fighting. They also “captured Aleksandrovka and used it as a hub for deep raids towards Lgov and Rylsk”, almost 30 miles into Russia.

Mr Zelensky used the apparent successes to ramp up pressure on Ukraine’s Western allies for further military support, saying his troops “are doing great on all fronts”, but needed “faster delivery of supplies”.

“There are no holidays in war. Decisions are needed, as are timely logistics for the announced aid packages,” he said. “I especially address this to the United States, the United Kingdom and France.”
