Russia and Ukraine exchanged over 200 prisoners of war on Tuesday, according to Ukrainian President Volodymyr Zelenskyy and Interfax, a Russian news agency.

During his daily evening address, Zelenskyy said 130 Ukrainians were "brought home from Russian captivity," including privates and sergeants from the army, navy and national guard.

"Just as we remember every corner of our country that is under occupation, we remember every single person in Russian captivity," he said.

Ninety Russians were released from the Ukrainian side back to Russia, though Russia said Ukraine originally agreed to release 160 Russians, Interfax reported.

"During the exchange of prisoners of war on Tuesday, the Ukrainian side agreed to return only 90 Russians, despite an earlier agreement on the exchange of '160 for 160,'" Tatyana Moskalkova, human rights ombudsman for the Russian Federation said, according to Interfax.

Up to 30,000 Russian soldiers have been killed or injured in Bakhmut over the last several months amid intense fighting in the eastern Ukrainian city, Western officials said in a briefing Tuesday.

The ratio of dead to injured was "unclear," said the officials, who described Ukraine’s refusal to withdraw from the city -- even though its forces are surrounded on three sides -- as "a sound tactic" given that "lots of Russians are being killed."

"What we're seeing is a horrific level of Russian casualties for minimal gains," they said, noting that an estimated 200,000 Russian soldiers have been killed or wounded overall since the war began.

In the past 24 hours, 244 Russian troops were killed and 315 wounded in Bakhmut, Serhiy Chevrevaty, a spokesman for Ukraine's eastern group of forces, said during a national telethon on Tuesday.

The officials refused to say how many Ukrainians have been killed or injured in and around Bakhmut but claimed it was "significantly lower."

They also were unable to put a clear time frame on when a Ukrainian withdrawal might come, though noted the possibility of a Ukrainian counteroffensive should not be ruled out.

Chinese President Xi Jinping hadn't even left Moscow when the drones started exploding. It came a matter of hours after Xi and Russian President Vladimir Putin proclaimed they were the ones who wanted to make "peace" in Ukraine.

Ukrainian officials say 21 lethal attack drones were launched overnight and into this morning by Russia, with 16 shot down by the Ukrainians.

An apartment block was hit in a town southeast of Kyiv, killing at least four people and injuring others, officials said. Russian officials claim Ukrainian soldiers were based there. The Ukrainians are calling it a "civilian" building.

Russian missiles later hit an apartment block in the heart of the southern Ukrainian city of Zaporizhzhia.

And in an apparent repost to the geopolitical theatrics in Moscow, Ukrainian President Volodymyr Zelenskyy visited his troops on Wednesday in the eastern Donbas, not far from the embattled city of Bakhmut, according to his officials.

Bakhmut has become a potent symbol of Ukrainian resistance and sacrifice and despite being surrounded on three sides Ukrainian forces inside the city are, after months of fighting there, still holding on.

Zelenskyy's office released video of him addressing troops and also visiting injured soldiers in a military medical facility in the region. He told troops their "destiny was difficult but important" because they were fighting to save the motherland.
