Russia Strikes Another Grain Terminal, Extending a Campaign Against Ukraines Ports

Russian forces struck a grain terminal in the southern Ukrainian city of Kherson, Ukrainian officials said on Saturday, extending a bombardment of the country’s infrastructure that has raised alarm about Kyiv’s ability to ship grain to the world.

President Volodymyr Zelensky of Ukraine has vowed to enhance air defenses around the port and the southern coast, but Kyiv’s resources are stretched thin and it faces difficult choices about where to deploy the limited number of air defense systems that can shoot down Russia’s most sophisticated missiles.

Ukraine continues to ask its Western allies to speed up the delivery of more air defense systems and warn that continued Russian bombardment could leave it without the necessary infrastructure to ship grain even if Black Sea shipping lanes open up. Moscow has struck Ukrainian ports near daily since pulling out of a deal last week that allowed Ukraine to ship its grain despite the war.

“In two or three months, we may not have a single port left,” Natalia Humeniuk, the spokeswoman for the Ukrainian military southern command, told French journalists this past week. “They want to dominate the Black Sea. They want to have a monopoly on grain,” she said.

On Saturday, Ms. Humeniuk said that Ukraine had taken measures to better protect the ports but warned that Russia may once again be adjusting its tactics before striking again.

The attack reported on Saturday hit a grain terminal in the Beryslav district and was just one of 29 attacks by Russian forces directed at Kherson in the past 24 hours, the Ukrainian military said. At least four civilians have been injured in those attacks, which were carried out with mortars, artillery, tanks and aircraft, the Ukrainian military said.

The bombardment of the port city came as tensions in the waters off the southern coast of Ukraine continued to rise, with Kyiv accusing Russian warships of threatening a civilian vessel and Russia’s Black Sea Fleet running drills off Ukraine’s southern coast this month. Moscow has warned that any ships sailing to Ukraine’s ports would be considered potentially hostile.

The Institute for the Study of War, a Washington-based think tank, said on Friday that the Russian naval posture in the Black Sea, which includes a warning that ships bound for Ukrainian ports would be potentially seen as carrying military cargo, was most “likely intentionally ambiguous to generate widespread concern about possible detention by the Russian navy or outright strikes on civilian vessels.”

“The Kremlin likely aims for this posturing to have a chilling effect on maritime activity so that Russian naval assets do not need to enforce an actual blockade of Ukrainian ports,” the analysts wrote.

Ukrainian border guards said they had intercepted a threatening message from a Russian warship communicating on an open channel to a civilian ship. The claim was amplified by Russian military bloggers who replayed a recording of the message. The message and the claim could not be independently verified.

Ukraine has vowed to step up its efforts to target Russian warships and vessels using Russian ports and has been working to expand its fleet of naval drones, which it has used to attack and harass the Russian Black Sea Fleet.

In an apparent recognition of the danger they pose, the Russian authorities announced a nighttime navigation ban for all small vessels near the Kerch Strait. This month, Ukraine used naval drones in an attack on the Kerch Strait Bridge, which links the Russian-occupied Crimean Peninsula to Russia, and is a primary supply route for Russian troops fighting in the south of Ukraine. The attack left the roadway badly damaged. The rail line over the bridge, however, is still functioning and Ukraine has vowed to continue mounting attacks.

African leaders meeting with President Vladimir V. Putin of Russia at a summit in St. Petersburg on Friday called for the revival of the Black Sea grain deal, saying that the continent was disproportionately affected by disruptions to the global food supply, while stopping short of directly criticizing Moscow for pulling out of the agreement.

“The grain deal must be extended for the benefit of all the peoples of the world, Africans in particular,” Moussa Faki Mahamat, the chairman of the African Union Commission, said at a Russia-Africa summit on Friday. “This conflict is now directly affecting us as well,” President Cyril Ramaphosa of South Africa said.

President Azali Assoumani of Comoros, the chairman of the African Union, said Russia’s promise of free grain for six African nations announced this week was “important but maybe not enough.”

But Mr. Putin at a news conference late Saturday offered no sign that he might rejoin the grain deal. Instead, he said that Russia stood to profit because global grain prices had risen after Russia exited the agreement.

“That means our companies will make more, which means we will get more in taxes,” Mr. Putin said. “If we get more in taxes, we will share part of our income with the poorest countries and will supply a certain volume of production for free.”

The African leaders also tried to advance their effort to broker a peace agreement between Russia and Ukraine, but Mr. Putin poured cold water on the idea. A cease-fire would be unworkable, he said, because Ukraine was mounting a counteroffensive. “The Ukrainian army is on the offensive. They are attacking,” Mr. Putin said. “Why ask us for a cease-fire?”

Here is what else is happening in the war:

• Zelensky Visit: The Ukrainian president said on Saturday that he had traveled to the Donetsk region in the country’s east “to congratulate our warriors” and to “honor their strength.” In one of a series of posts on social media accompanied by photographs with soldiers, he said that he had heard a commander’s report but could not share details of current operations.

  Along with pushing toward the south, Ukraine is trying to advance eastward in the direction of Bakhmut, which fell to Russian forces in May after months of bloody fighting.

• Zaporizhzhia Strike: Two people were killed and a third was injured when a Russian missile struck an open area in the city of Zaporizhzhia on Saturday, the secretary of the city council, Anatolii Kurtiev, said on Telegram. Mr. Kurtiev added that the blast had blown out the windows of apartments in 13 high-rise buildings nearby and that the city had social workers and other support services on the scene to help residents who were affected.

• North Korea and Russia: A visit by Russia’s defense minister, Sergei K. Shoigu, this past week to North Korea, during which he met with the country’s leader, Kim Jong-un, was probably a bid to secure additional weapons and political support for the war in Ukraine, Secretary of State Antony J. Blinken said on Saturday.

  “We’re seeing Russia desperately looking for support for weapons wherever it can find them,” Mr. Blinken said, responding to a reporter’s question in Brisbane, Australia. “We see that in North Korea. We see that as well with Iran.”
