The Ukrainian sniper adjusted his scope and fired a.50-caliber bullet at a Russian soldier across the Dnieper River. Earlier, another Ukrainian used a drone to scan for Russian troops.

Two weeks after retreating from the southern city of Kherson, Russia is pounding the town with artillery as it digs in across the Dnieper River.

Ukraine is striking back at Russian troops with its own long-distance weapons, and Ukrainian officers say they want to capitalize on their momentum.

The Russian withdrawal from the only provincial capital it gained in nine months of war was one of Moscow’s most significant battlefield losses. Now that its troops hold a new front line, the army is planning its next move, the Ukrainian military said through a spokesman.

Ukrainian forces can now strike deeper into the Russian-controlled territories and possibly push their counteroffensive closer to Crimea, which Russia illegally captured in 2014.

Russian troops continue to establish fortifications, including trench systems near the Crimean border and some areas between the Donetsk and Luhansk regions in the east.

In some locations, new fortifications are up to 60 kilometers (37 miles) behind the current front lines, suggesting that Russia is preparing for more Ukrainian breakthroughs, according to the British Ministry of Defense.
