Moscow, RUSSIA (AFP) — Russia vowed Sunday to “intensify” its strikes on Kyiv in response to Ukrainian drone attacks on Moscow, as an exit poll showed the ruling United Russia party on course to win tightly controlled parliamentary elections.

Ukraine fired waves of drones at Moscow and the surrounding region on the final day of voting, killing two people and setting an oil refinery ablaze, officials said.

Russia’s defence ministry accused Ukraine of attempting to “disrupt the democratic will of Russian citizens” and vowed a response.

An exit poll published by a State-run pollster showed United Russia on course to win 49.4 per cent of the vote, around the same it achieved in the previous election.

“In response to the Kyiv regime’s attacks on civilian targets within Russia, the Russian army will continue and intensify its high-accuracy strikes against military targets in Kyiv,” the Russian defence ministry said.

The attack was the largest on Moscow since the Kremlin launched its Ukraine offensive in 2022 and involved some 1,600 drones, 450 of which were aimed directly at the capital, Moscow Mayor Sergei Sobyanin said.

Images showed a gaping hole in a multi-storey apartment building on the outskirts of the capital, while another showed black smoke pouring from what appeared to be an oil refinery.

Ukrainian President Volodymyr Zelensky praised the attacks, saying: “Our long-range responses had a very significant impact in the Moscow region last night.

“One of Russia’s key oil industry facilities and the aggressor’s logistics facility were hit. These are billions of dollars that sustain the war machine,” he said on X.

At least two people were killed — a 44-year-old woman and an elderly man — in two separate locations, Moscow regional Governor Andrey Vorobyov said.

A fire triggered by a drone crashing into a 21-storey building also led to 400 people being evacuated, Vorobyov added.

Ukraine has targeted Russian infrastructure with drones throughout the war, in retaliation for Russian bombardment of its own towns and cities.

The parliamentary vote, which decides all 450 seats in Russia’s lower house State Duma, was Russia’s first since launching its Ukraine offensive.

A exit poll by the state-owned Russian Public Opinion Research Center (VCIOM) showed United Russia winning 49.4 percent, with the Communist Party and nationalist LDPR party on 14.2 and 10.7 per cent respectively.

Former President Dmitry Medvedev, who chairs United Russia, said his party appeared to have “performed admirably”.

“We must now put the president’s decisions into practice,” he was quoted as saying by the State
RIA news agency.

All other parties contesting supported the war and Putin, and the exit poll did not include electronic voting and military ballots.

“For that reason I believe United Russia’s result will be higher, whilst that of the opposition parties will be lower,” VCIOM director Valery Fedorov said.

Yabloko – a liberal party that had called for an end to the fighting – was barred from running its federal list by Russia’s Supreme Court, although its candidates remained on the ballot in some single-mandate constituencies.

Putin had urged Russians to take part, casting the vote as a show of support for Moscow’s troops and an “answer to those who want to weaken Russia”.The Kremlin’s chief political opponents have been driven into exile, while Putin’s main rival, Alexei Navalny, died in an Arctic prison in 2024.

The first official results and turnout will be expected on Monday morning.
