Russian President Vladimir Putin vowed Friday to press his attack on Ukraine despite Kyiv’s latest counteroffensive and warned that Moscow could ramp up its strikes on the country’s vital infrastructure if Ukrainian forces target facilities in Russia.

Speaking to reporters Friday after attending a summit of the Shanghai Cooperation Organization in Uzbekistan, Putin said the “liberation” of Ukraine’s entire eastern Donbas region remained Russia’s main military goal and that he sees no need to revise it.

“We aren’t in a rush,” the Russian leader said, adding that Moscow has only deployed volunteer soldiers to fight in Ukraine. Some hard-line politicians and military bloggers have urged the Kremlin to follow Ukraine’s example and order a broad mobilization to beef up the ranks, lamenting Russia’s manpower shortage.

Russia was forced to pull back its forces from large swaths of northeastern Ukraine last week after a swift Ukrainian counteroffensive. Ukraine’s move to reclaim control of several Russian-occupied cities and villages marked the largest military setback for Moscow since its forces had to retreat from areas near the capital early in the war.
