Ukraine security officials said on Saturday that two Russian soldiers have died, and dozens became ill after being poisoned by stuffed buns handed to them by Ukrainians near Kharkiv.

Citizens in the city of Izium presented cakes and other sweets to soldiers from the 3rd Motor Rifle Division, according to Ukraine's Main Intelligence Directorate.

"As a result, two invaders were poisoned and died at the same time, and another 28 were rushed to the hospital," officials posted on Facebook.

The troops' conditions at the hospital were uncertain. As per Ukraine officials, another 500 men who fought for Russian President Vladimir Putin have been hospitalized due to alcohol intoxication. 

It's unsure whether the Russian troops got their hands on the liquor from Ukrainians. According to Ukrainian officials, Russia has classified the incidents as "non-combat losses."

Meanwhile, Russia conducted airstrikes on the Ukrainian cities of Kharkiv and Odessa on Sunday. Over the last day, Russian forces fired more than 20 strikes on Kharkiv and its suburbs in the country's northeast, as stated by the regional governor Oleh Synyehubov.

"Four people were injured in a missile attack on the city of Lozovo, while Russian tanks bombarded a medical facility in the village of Balakliia," Synyehubov said.

The Russian military reportedly launched an attack on the Black Sea port of Odessa in southern Ukraine on Sunday morning. The targets, according to the Russian army, were an oil-processing plant and fuel stockpiles in and near Odessa, the country's major port and home to its navy.

As Russian soldiers retreated from Kyiv and its outskirts, Ukrainian officials reported they discovered brutalized bodies of women, children, and local government officials in the small city of Bucha, nearby Kyiv. 

Some of the ladies were allegedly raped and set on fire, according to Ukraine.

"There are bodies of dead guys that show evidence of torture. Their hands were tied at the back, and they were slain by back-of-the-head bullets," said Oleksiy Arestovych, a spokesman for Ukrainian President Volodymyr Zelensky.

The terrible findings appear "absolutely like war crimes," as per Sergey Nikiforov, who told the BBC that the Kremlin had initially denied committing war crimes in Ukraine's "special military exercise."

Last week, Russia promised to "dramatically" lessen its strikes in the vicinity of Kyiv and Chernihiv. However, Ukraine has warned that this does not mean the cities will never be targets again, and the United States and its allies speculated that the move implies that Putin is repositioning.
