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.

The United States announced an additional $2 billion military aid package for Ukraine on Friday, as the Eastern European country marks the one-year anniversary of Russia's full-scale invasion.

The new aid package includes more missiles for Ukraine's U.S.-supplied High Mobility Artillery Rocket Systems (HIMARS), additional 155mm artillery ammunition, more Switchblade one-way drones and other military equipment, according to the U.S. Department of Defense.

"One year into a war of aggression waged by a permanent member of the U.N. Security Council, our allies and partners worldwide stand united and resolute," U.S. Secretary of Defense Lloyd Austin said in a statement. "Putin's reckless, illegal war is not just an all-out assault on Ukraine's sovereignty and a historic threat to European security. It is also a direct attack on the system of rules, institutions, and laws that the world built at such great cost after World War II -- a system that rejects aggression and respects the rights of all countries, big and small."

The additional aid is being provided under the Ukraine Security Assistance Initiative (USAI) plan, meaning this equipment and artillery have to be made from scratch before being delivered, which will take time. This is different from the other aid packages that come from existing U.S. military stockpiles and get delivered faster.

With the new aid package, the Biden administration has now provided $31.8 billion in assistance to Ukraine since Russia's war began on Feb. 24, 2022.

"Putin thought that Ukraine’s defenses would collapse, that America's resolve would falter, and that the world would look the other way. He was wrong," Lloyd said. "One year later, Ukraine's brave defenders have not wavered, and neither has our commitment to support them for as long as it takes. Despite the Kremlin's campaign of cruelty, the people of Ukraine have shown stunning bravery, skill, and fortitude. Today and every day, we stand by the courageous Ukrainians fighting to defend their country, and we mourn with those who have lost their loved ones in Moscow's monstrous and unnecessary war."

"Difficult times may lie ahead, but let us remain clear-eyed about what is at stake in Ukraine," he added. "And let us remain united in purpose and in action -- and steadfast in our commitment to ensure that a world of rules and rights is not replaced by one of tyranny and turmoil."
