President Volodymyr Zelenskiy said on Friday he had visited the northern Sumy region, from where Ukraine launched a major incursion into the neighbouring Russian Kursk region.

A Russian military counterattack in the Kursk region turns disastrous as Russian tanks get stuck in their own defensive structures.

The Russian column got stuck in anti-tank traps—a trench and a line of concrete obstacles—that the Russians had built prior to the Ukrainian invasion of Kursk in early August. There are two main Russian-built defensive structures outside Plekhovo—the anti-tank traps and a nearby infantry trench complex.
