SLOVIANSK, Ukraine (AP) — Russia on Thursday pulled back its forces from a strategically placed Black Sea island where they have faced relentless Ukrainian attacks, but kept up its push to encircle the last bulwark of Ukraine’s resistance in the eastern province of Luhansk.

Russia’s Defense Ministry said it withdrew its forces from the Zmiyinyy (Snake) Island off Ukraine’s Black Sea port of Odesa in what it described as a “goodwill gesture.” Ukraine’s military said the Russians fled the island in two speedboats following a barrage of Ukrainian artillery and missile strikes.

Russian Defense Ministry spokesman Lt. Gen. Igor Konashenkov insisted that the withdrawal was intended to demonstrate that “the Russian Federation wasn’t hampering the United Nations’ efforts to establish a humanitarian corridor for taking agricultural products from the territory of Ukraine.”

Ukraine and the West have accused Russian of blockading Ukrainian ports to prevent exports of grain, contributing to the global food crisis. Russia has denied the accusations and charged that Ukraine needs to remove sea mines from the Black Sea to allow safe navigation.

Turkey has sought to broker a deal on unblocking grain exports from Ukraine, but the talks have dragged on without any sign of quick progress, with Kyiv voicing concern that Russia could use the deal to launch an attack on Odesa.

Russia took control of the island that sits along a busy shipping lane in the opening days of the war in apparent hope to use it as a staging ground for an attack on Odesa.

The island came to epitomize the Ukrainian resistance to the Russian invasion, when Ukrainian troops there received a demand from a Russian warship to surrender or face bombardment. “Russian warship,” the answer came back, “go (expletive) yourself.”

The Ukrainian defenders of the island were captured by the Russians but later freed as part of a prisoner exchange.

After the island was taken, the Ukrainian military relentlessly bombarded a small Russian garrison and air defense assets stationed there.

— In the east of Ukraine on Thursday, Moscow kept up its push to take control of the entire Donbas region. It is focused on the city of Lysychansk, the last remaining Ukrainian stronghold in the Luhansk province. Russian troops and their separatist allies control 95% of Luhansk and about half of Donetsk, the two provinces that make up the mostly Russian-speaking Donbas.

The Ukrainian General Staff said that the Russian troops were shelling Lysychansk and clashing with Ukrainian defenders around an oil refinery on the edge of the city.

Luhansk Gov. Serhiy Haidai said Russian reconnaissance units tried to enter Lysychansk Wednesday, but were repelled by Ukrainian forces. He said the Russians were trying to block a highway used to deliver supplies and fully encircle the city.

“The Russians have thrown practically all their forces to seize the city,” Haidai said.

— Speaking on a visit to Turkmenistan early Thursday, Russian President Vladimir Putin said his goals in Ukraine haven’t changed since the start of the war. He said they were “the liberation of the Donbas, the protection of these people and the creation of conditions that would guarantee the security of Russia itself.” He made no mention of his original stated goals to “demilitarize” and “de-Nazify” Ukraine.

He denied Russia had adjusted its strategy after failing to take Kyiv in the early stage of the conflict. “As you can see, the troops are moving and reaching the marks that were set for them for a certain stage of this combat work. Everything is going according to plan,” Putin said at a news conference in Turkmenistan.

— Funerals were to be held Thursday for some of the 18 people confirmed killed by Monday’s Russian missile strike on a busy shopping mall in the central city of Kremenchuk. Crews continued to search through the rubble in search of another 20 people who remain missing.

Ukrainian State Emergency Services press officer Svitlana Rybalko told The Associated Press that along with the 18 bodies, investigators found fragments of eight more bodies. It was not immediately clear whether that meant there were more victims. A number of survivors suffered severed limbs.

— After the attack on the mall, Ukrainian President Volodymyr Zelenskyy accused Russia of becoming a “terrorist” state. On Wednesday, he reproached NATO for not embracing or equipping his embattled country more fully.

He asked for more modern artillery systems and other weapons and warned the NATO leaders they either had to provide Ukraine with the help it needed to defeat Russia or “face a delayed war between Russia and yourself.”

On Thursday, Sweden announced plans to send more military support to Ukraine, including anti-tank weapons, support weapons and demining equipment that it says Kyiv had requested. “It is important that the support to Ukraine from the democratic countries in Europe is continuous and long-term,” Defense Minister Peter Hultqvist said, according to the Swedish news agency TT.

Hultqvist didn’t say when and how the equipment would be delivered . Sweden was invited at a NATO summit this week to join the Western military alliance.

— Russia, shunned by the West, has been intent on bolstering ties elsewhere. On Thursday, Iranian state media said that Iran has proposed expanding financial exchanges with Russia as well as cooperating in the energy field within a framework independent of the Western financial exchange system, while both countries are under heavy sanctions.

Iranian President Ebrahim Raisi and Putin met on the sidelines of a summit of the Caspian Sea Littoral States in Ashgabat, Turkmenistan, state-run IRNA news agency reported Thursday.

Putin was quoted as saying that the volume of trade and overall economic relations between the two countries has increased in recent months and that this path should continue.

— The death toll from Wednesday’s Russian missile strike on an apartment building in the southern city of Mykolaiv has risen to six, according to Gov. Vitaliy Kim. Another six people were wounded. Mykolaiv is a major port and seizing it — as well as Odesa farther west — would be key to Russia’s objective of cutting off Ukraine from its Black Sea coast.
