POKROVSK, Ukraine (AP) — European leaders blasted Russia’s decision to cut natural gas shipments to Poland and Bulgaria as “blackmail,” saying the cutoff and the Kremlin’s warning that it might cease shipments to other countries is a failed attempt to divide the West over its support for Ukraine.
Russia’s move Wednesday to use its most essential export as leverage marked a dramatic escalation in the economic war of sanctions and countersanctions that has unfolded in parallel to the fighting on the battlefield.
The tactic against the two EU and NATO members could eventually force targeted nations to ration gas and deal another blow to economies suffering from rising prices. At the same time, it could deprive Russia of badly needed income to fund its war effort.
Poland has been a major gateway for the delivery of weapons to Ukraine and confirmed this week that it is sending the country tanks. Just hours before Russia’s state energy giant Gazprom acted, Poland announced a new set of sanctions against the company and other Russian businesses and oligarchs.
Bulgaria, under a new liberal government that took office last fall, has cut many of its old ties to Moscow and likewise supported punitive measures against the Kremlin. It has also hosted Western fighter jets at a new NATO outpost on Bulgaria’s Black Sea coast.
The gas cuts do not immediately put the two countries in any dire trouble. Poland, especially, has been working for many years to line up other suppliers, and the continent is heading into summer, making gas less essential for households.
Also, Russian gas deliveries to both Poland and Bulgaria were expected to end later this year anyway.
Still, the cutoff and the Kremlin warning that other countries could be next sent shivers of worry through the 27-nation European Union. Germany, the largest economy on the continent, and Italy are among Europe’s biggest consumers of Russian natural gas, though they, too, have been taking steps to reduce their dependence on Moscow.
“It comes as no surprise that the Kremlin uses fossil fuels to try to blackmail us,” said EU Commission President Ursula von der Leyen. “Today, the Kremlin failed once again in his attempt to sow division amongst member states. The era of Russian fossil fuel in Europe is coming to an end.”
Gazprom said it shut off the two countries because they refused to pay in rubles, as President Vladimir Putin has demanded of “unfriendly” nations. The Kremlin said other countries may be cut off if they don’t agree to the payment arrangement.
Most European countries have publicly balked at Russia’s demand for rubles, but it is not clear how many have actually faced the moment of decision so far. Greece’s next scheduled payment to Gazprom is due on May 25, for example, and the government must decide then whether to comply.
Polish Prime Minister Mateusz Morawiecki told his country’s parliament that he believes Poland’s support for Ukraine — and the new sanctions imposed by Warsaw on Tuesday — were the real reasons behind the gas cutoff.
Bulgarian Prime Minister Kiril Petkov called the suspension blackmail, adding: “We will not succumb to such a racket.”
Ukrainian President Volodymyr Zelenskyy said that Russia views gas as a weapon for political blackmail and “sees a united Europe as a target.”
On the battlefield, fighting continued in the country’s east along a largely static front line some 300 miles (480 kilometers) long.
Russia claimed its missiles hit a batch of weapons that the U.S. and European nations had delivered to Ukraine. One person was killed and at least two were injured when rockets hit a residential neighborhood in Kharkiv.
Western officials, speaking on condition of anonymity to discuss intelligence findings, said Russia has made slow progress in the eastern Donbas region, with “minor gains,” including the capture of villages and small towns south of Izyum and on the outskirts of Rubizhne.
Serhiy Haidai, the governor of the Luhansk region, conceded that Russia has made some progress in its advance on Rubizhne through its nearly constant bombardment, but that Ukrainian troops are fighting back and retreating only when there is nothing left to defend.
“There is no point in staying on territory that has been fired on so often that every meter is well known,” he said.
Maxim, a Ukrainian tank commander in the Donbas who didn’t give his last name, offered his rationale for why Ukrainian forces have been able to hold back the better-equipped Russian army: “The strength is not in the tank; the strength is in the people.”
The Western officials said some Russian troops have been shifted from the gutted southern port city of Mariupol to other parts of the Donbas. But some remain in Mariupol to fight Ukrainian forces holed up at the Azovstal steel plant, the last stronghold in the city. About 1,000 civilians were said to be taking shelter there with an estimated 2,000 Ukrainian defenders.
“The situation is very difficult. There are huge problems with water, food,” Serhii Volynskyi, commander of the marine unit inside the plant, said in a Facebook video message. He said hundreds of fighters and civilians were wounded and in need of medical help, and those inside included children, older people and disabled people.
In the Black Sea port city of Kherson, which Russian forces have occupied since early in the war, a series of explosions boomed late Wednesday near the television tower and at least temporarily knocked Russian channels off the air, Ukrainian and Russian news organizations reported.
Just across the border from the Donbas in Russia, an ammunition depot in the Belgorod region burned after several explosions were heard, the governor said. Blasts were also reported in Russia’s Kursk region near the border, and authorities in Russia’s Voronezh region said an air defense system shot down a drone.
Earlier this week, an oil storage facility in the Russian city of Bryansk was engulfed by fire.
Ukrainian presidential adviser Mykhailo Podolyak hinted at the country’s involvement in the fires, saying in a Telegram post that “karma (is) a harsh thing.”
With the help of Western arms, Ukrainian forces managed to thwart Russian forces’ attempt to storm Kyiv. Moscow now says its focus is the capture of the Donbas, Ukraine’s mostly Russian-speaking industrial heartland.
A defiant Putin vowed Russia will achieve its military goals, telling parliament, “All the tasks of the special military operation we are conducting in the Donbas and Ukraine, launched on Feb. 24, will be unconditionally fulfilled.”
