Russian authorities have rejected a price cap on the country's oil set by Ukraine's Western supporters and threatened on Saturday to stop supplying the nations that endorsed it.
Australia, Britain, Canada, Japan, the United States and the 27-nation European Union agreed on Friday to cap what they would pay for Russian crude oil at $60 US per barrel. The limit is set to take effect on Monday, along with an EU embargo on Russian oil shipped by sea.
Kremlin spokesperson Dmitry Peskov said Russia needed to analyze the situation before deciding on a specific response but that it would not accept the price ceiling. Russia's permanent representative to international organizations in Vienna, Mikhail Ulyanov, warned that the cap's European backers would come to rue their decision.
"From this year, Europe will live without Russian oil," Ulyanov posted on Twitter. "Moscow has already made it clear that it will not supply oil to those countries that support anti-market price caps. Wait, very soon the EU will accuse Russia of using oil as a weapon."
Russia has previously said it will not supply oil to countries that implement the cap.
Ukraine calls for lower price cap
The office of Ukrainian President Volodymyr Zelenskyy, meanwhile, called on Saturday for a lower price cap, saying the one adopted by the EU and the G7 leading economies didn't go far enough.
"It would be necessary to lower it to $30 US in order to destroy the enemy's economy faster," Andriy Yermak, the head of Zelenskyy's office, wrote on the Telegram messaging service, staking out a position also favoured by Poland — a leading critic of Russian President Vladimir Putin's war in Ukraine.
Under Friday's agreements, insurance companies and other firms needed to ship oil would only be able to deal with Russian crude if the oil is priced at or below the cap. Most insurers are located in the EU and the United Kingdom, and they could be required to observe the ceiling.
Russia's crude has already been selling for about $60 US a barrel, a deep discount from international benchmark Brent, which closed Friday at $85.42 US per barrel.
The Russian Embassy in Washington insisted that Russian oil "will continue to be in demand" and criticized the price limit as "reshaping the basic principles of the functioning of free markets." A post on the embassy's Telegram channel predicted the per-barrel cap would lead to "a widespread increase in uncertainty and higher costs for consumers of raw materials."
The price cap aims to put an economic squeeze on Russia and further crimp its ability to finance a war that has killed an untold number of civilians and fighters, driven millions of Ukrainians from their homes and weighed on the world economy for more than nine months.
Missile strikes reported in Donetsk
The General Staff of the Ukrainian Armed Forces reported that since Friday, Russia's forces had fired five missiles, carried out 27 airstrikes and launched 44 shelling attacks against Ukraine's military positions and civilian infrastructure.
Kyrylo Tymoshenko, the deputy head of the president's office, said the attacks killed one civilian and wounded four others in Eastern Ukraine's Donetsk region. According to Britain's Defence Ministry, Russian forces "continue to invest a large element of their overall military effort and firepower" around the small Donetsk city of Bakhmut, which they have spent weeks trying to capture.
In southern Ukraine's Kherson province, whose capital city of the same name was liberated by Ukrainian forces three weeks ago following a Russian retreat, Gov. Yaroslav Yanushkevich said evacuations of civilians stuck in Russian-held territory across the Dnipro River would resume temporarily.
Russian forces pulled back to the river's eastern bank last month. Yanushkevich said a ban on crossing the waterway would be lifted during daylight hours for three days for Ukrainian citizens who "did not have time to leave the temporarily occupied territory." His announcement cited a "possible intensification of hostilities in this area."
Kherson is one of four regions that Putin illegally annexed in September and vowed to defend as Russian territory. From their new positions, Russian troops have regularly shelled Kherson city and nearby infrastructure in recent days, leaving many residents without power. Running water remained unavailable in much of the city.
The other regions annexed in violation of international law are Donetsk, Luhansk and Zaporizhzhia.
Ukrainian authorities also reported intense fighting in Luhansk and Russian shelling of northeastern Ukraine's Kharkiv region, which Russia's soldiers mostly withdrew from in September.
The mayor of the city of Kharkiv, which remained under Ukrainian control during Russia's occupation of other parts of the region, said some 500 apartment buildings were damaged beyond repair, and nearly 220 schools and kindergartens were damaged or destroyed. He estimated the cost of the damage at $9 billion US.
