KYIV, Ukraine — Russia seized on the mass give up of Ukrainian troops at a Mariupol metal plant as a propaganda present on Wednesday, transferring to falsely label them as terrorists and create a parallel narrative to Ukraine’s portrayal of Russian troopers as heinous conflict criminals.

The mass surrender, which ended the longest battle of the three-month-old conflict, was depicted by the Russians as a wonderful turning level in a battle that Western navy analysts and rights teams have described as disastrous for the Kremlin and its forces, which have bombed Ukraine indiscriminately and been accused of different atrocities.

Photographs of the surrendering Ukrainians had been publicized by the Russians simply as a Russian soldier pleaded responsible in a Ukrainian courtroom to fatally capturing an unarmed civilian, in a extensively adopted case.

In Brussels, Turkey difficult efforts by NATO to shortly think about membership bids by Sweden and Finland, blocking an preliminary vote and presenting a listing of grievances associated to Kurdish teams that it considers terrorists.

Whereas Turkey indicated that it might not finally oppose membership for Sweden and Finland, its objections are slowing a course of that the West had hoped would shortly strengthen European defenses in opposition to additional aggression by President Vladimir V. Putin of Russia.

Turkey’s transfer got here in opposition to the backdrop of a separate frustration for the West’s challenges to Mr. Putin: Prime Minister Viktor Orban of Hungary, another authoritarian leader, has stalled a proposed European Union embargo of Russian oil.

Ukraine had initially described the mass give up of the troopers at Mariupol’s Azovstal metal plant, which its navy ordered Monday night time, as the one different to their near-certain loss of life in opposition to hopeless odds, and as a prelude to a prisoner trade.

However there was no discuss from Moscow of swapping any captives, and by Wednesday it was clear that the Kremlin supposed to make use of the prisoners for different functions.

Russian commentators celebrated the autumn of the metal plant and, particularly, the seize of members of the Azov battalion, a Ukrainian regiment with roots as a far-right group, which Mr. Putin has exploited to fictitiously painting the invasion as a battle to rid Ukraine of Nazis.

The Russian Supreme Courtroom stated it might maintain a listening to subsequent week on whether or not to declare the Azov group a “terrorist group,” which might give Moscow cowl to deprive the prisoners of rights. Russia has stated that 959 troopers within the plant surrendered, about 800 of them from the Azov battalion. It’s believed that as much as 1,000 extra troopers stay contained in the plant.

Maria V. Zakharova, a Russian International Ministry spokeswoman, stated that Azov troopers had dedicated conflict crimes through the use of kindergartens and medical facilities to retailer ammunition and through the use of civilians as human shields — accusations that echoed these leveled in opposition to Russian troops by the West.

A number of the prisoners had been transferred to pretrial detention within the city of Yelenovka, within the Russia-controlled jap Ukrainian area of Donetsk, Ms. Zakharova stated. She accused Ukraine’s forces of getting fired rockets on the facility that held them.

Ms. Zakharova stated she had no details about a prisoner trade with Ukraine, and that these requiring medical consideration had been receiving it. Russia launched a video of hospitalized captive troopers in a separatist-held metropolis east of Mariupol.

Amnesty Worldwide urged Russia to respect the rights of the captives, saying they’d been “dehumanized by Russian media” and portrayed by Mr. Putin’s propagandists as neo-Nazis, which “raises critical considerations over their destiny as prisoners of conflict.”

Ms. Zakharova stated that Russia had inspired the troopers to depart the plant for days, and he or she faulted Ukraine for having waited so lengthy to organize them to give up. “For the time being, a very powerful factor is that everyone exits,” she stated.

Complicating efforts by Ukraine to barter a prisoner trade, the speaker of the Russian Parliament, Vyacheslav Volodin, stated lawmakers would think about a ban on “exchanges of Nazi criminals.”

Russia’s transfer to deal with the captives as conflict criminals got here as a Russian soldier pleaded responsible in a Kyiv court docket to having fatally shot a 62-year-old man on a bicycle — a killing that could possibly be thought of a conflict crime.

Requested by the presiding choose whether or not he accepted his guilt, the soldier, Sgt. Vadim Shyshimarin, 21, stated: “Sure.”

“Totally?” the choose requested. “Sure,” the sergeant replied.

The sergeant had admitted to Ukrainian investigators that he fired the Kalashnikov rifle that had killed the person, Oleksandar Shelipov, prosecutors stated.

He advised investigators in a videotaped assertion that he and 4 different servicemen had stolen a automotive at gunpoint and had been fleeing Ukrainian forces after they noticed Mr. Shelipov on a bicycle, speaking on a cellphone. Sergeant Shyshimarin stated he had been ordered to kill the person so he wouldn’t report them.

The sergeant, who’s dealing with 10 to fifteen years in jail, was charged below Ukrainian statutes with violating “the legal guidelines and customs of conflict, mixed with premeditated homicide,” prosecutors said. He was not charged with a conflict crime below worldwide regulation.

The trial, a part of Ukraine’s effort to doc atrocities and determine perpetrators, drew intense curiosity. On Wednesday, the courtroom and an overflow room had been crowded with members of the native and worldwide information media, and the proceedings had been broadcast on YouTube.

Authorized consultants stated conflict crimes prosecutions in opposition to senior commanding officers are harder and may take far longer as a result of their connections to the crime have to be proved in court docket. On this case, Sergeant Shyshimarin had been accused of really firing the deadly shot.

The prosecution was extraordinary partly as a result of it proceeded regardless of its potential to disrupt and even halt future prisoner exchanges between Ukraine and Russia.

“The Russians could now determine to carry circumstances in opposition to Ukrainian P.O.W.s,” stated Alex Whiting, a conflict crimes prosecutor who’s a visiting professor at Harvard Regulation Faculty. “This exhibits how the atrocity crimes being dedicated by Russian forces, and Ukraine’s dedication to prosecute them, are a lot the focus proper now.”

The Ukrainian prosecutor within the trial, Andriy Sinyuk, described it as an “unprecedented process” by which “a serviceman of a special nation is accused of murdering a civilian of Ukraine.”

A Kremlin spokesman, Dmitri S. Peskov, dismissed the proceedings, telling reporters that the accusations leveled in opposition to Russian troopers by Ukraine had been “merely pretend or staged.”

“We nonetheless don’t have any data,” Mr. Peskov stated. “And the flexibility to offer help because of the lack of our diplomatic mission there may be additionally very restricted.”

Whilst Turkey raised considerations about shortly admitting Sweden and Finland to NATO, President Biden on Wednesday formally endorsed each of their functions. He additionally issued a rigorously worded warning to Russia that the US would assist defend each international locations whereas their functions are pending.

In blocking an early procedural vote on the functions, Turkey’s president, Recep Tayyip Erdogan, gave the impression to be calculating that his cooperation was at a premium at a second of worldwide disaster. NATO operates by consensus, giving any member political leverage over key choices.

Soner Cagaptay, director of the Turkish Analysis Program on the Washington Institute, stated Mr. Erdogan was possible angling for concessions earlier than a NATO summit in June, and was possible searching for Sweden to take a stronger stand in opposition to Kurdish teams that Turkey regards as linked to the Kurdistan Employee’s Get together, or P.Ok.Ok., which launched a violent separatist motion in Turkey within the early Eighties.

Mr. Erdogan can also be in search of to unlock gross sales of American F-16 fighter jets to Turkey, Mr. Cagaptay stated.

In an tackle to lawmakers in Turkey’s Parliament on Wednesday, Mr. Erdogan stated the outpouring of assist for Ukraine, which he has usually supported, was “bittersweet.”

“As a result of we, as a NATO ally who struggled with terror for years, whose borders had been harassed, huge conflicts occurred simply subsequent door, have by no means seen such an image,” he stated.

Turkey’s international minister, Mevlut Cavusoglu, signaled that his nation wouldn’t cease Sweden and Finland from becoming a member of NATO and would work to “overcome the variations by way of dialogue and diplomacy.”

“We perceive their safety considerations, however Turkey’s safety considerations must be additionally met,” Mr. Cavusoglu advised Secretary of State Antony J. Blinken forward of a gathering on the United Nations in New York.
