Russia has quietly started a new round of mobilization and plans to bring in more North Korean troops, Ukrainian President Volodymyr Zelenskyy said. He cited a new report from Ukraine's military intelligence. The same day, the Kremlin published a decree enlarging Russia's army for the fourth time this year.

Russia widens recruitment at home and abroad

Zelenskyy spoke in his evening address on 28 September, after a briefing from Ukraine's military intelligence (HUR).

"In effect, the Russians have already begun additional mobilization—they are increasing the number of people they recruit through various means," he said.

Moscow also plans to recruit more foreigners, Zelenskyy said. He urged the governments of countries whose citizens Russia recruits to counter it, and said Kyiv would inform each of them.

Ukraine says Russia has been losing soldiers faster than contract recruitment replaces them. If so, an unannounced call-up lets the Kremlin refill its ranks without a formal draft. ISW says Putin may hold off on such a draft until he sees whether his strikes work. Ukrainian intelligence had expected Russia to announce a mass mobilization after this month's State Duma elections.

More than 8,000 North Koreans in Russia, 10,000 more in preparation

More than 8,000 North Korean troops are currently on Russian territory, Zelenskyy said. Pyongyang is selecting another 10,000 for training and deployment to Russia, he added.

Russia is paying, among other things, with technology, according to Zelenskyy. North Korea has launched production of Shahed-type attack drones with Russian technical support, he said.

That is a step beyond what Kyiv reported in June 2025. Moscow and Pyongyang had then only agreed to start preparing such production. In August, Zelenskyy warned that Russia could receive up to 50,000 North Korean troops.

Kremlin raises the army's size again

Putin's decree sets the authorized strength of Russia's armed forces at 2,441,630, including 1,550,500 military personnel, Vedomosti reported. The decree gives no reason.

The order adds 15,500 troops and is the fourth such increase this year, Euronews said. Since March, the combined increase has reached 47,860 soldiers. Putin's 2022 "partial mobilization" decree also remains in force, the outlet noted.

Moscow keeps denying a call-up

In early September, Putin claimed that reports of a coming mobilization were "complete nonsense" and "an information attack on Russia." Russian officials gave similar assurances days before the 2022 call-up.

Ukraine's military and foreign intelligence had earlier said that Russia's General Staff prepared a scenario to mobilize 600,000 people over 2026 and 2027, 300,000 each year.

Russian authorities left residents in and around Moscow without air raid sirens or phone alerts during Ukraine's largest combined strike on Moscow Oblast, apparently to guard turnout at Russia's parliamentary elections, the Institute for the Study of War (ISW) said. The silence angered residents and even pro-war commentators as a major oil refinery burned.

For most of this war, Russia has handled strikes on its cities as a routine to be announced, warned about, and waited out. Withholding warnings during the heaviest raid yet, in the middle of a national vote, suggests authorities will trade residents' safety for the look of a calm election when a political milestone is on the line.

Sirens stayed off during the biggest raid

Ukraine hit strategic sites across the Moscow area overnight on 19-20 September, the last day of Russia's State Duma vote. Moscow Oblast officials did not switch on air alert sirens or send the SMS warnings they had used during far smaller attacks. They quietly restricted mobile service without major public notice. Ukraine struck oil and logistics targets, not polling stations, according to the experts, and authorities appeared to place high turnout above protecting civilians.

Moscow Oblast residents complained that no alert reached them, some posting on the Telegram channel of regional Governor Andrei Vorobyov before it closed comments. A prominent Kremlin-linked military blogger attacked the official response, saying it erodes public trust and that cutting mobile service does "not really help."

What the drones hit

Ukraine's General Staff reported striking the Gazpromneft-Moscow Oil Refinery in the city's Kapotnya district, one of Russia's largest plants, causing a large fire. Ukrainian manufacturer Fire Point said its FP-1 drones completely shut down the refinery, with all primary processing units damaged.

Governor Andrei Vorobyov claimed air defenses countered 249 drones across 17 municipal districts. The strike was part of Ukraine's widening campaign against the fuel sector funding Russia's war, with about a fifth of Russian refining capacity offline.
