Explosions were heard and felt in the cities of Odesa and Kherson and the regions of Zaporizhzhia and Donetsk on Tuesday evening, officials and people on the ground in Ukraine reported on social media channels.

During the attack on Odesa, Ukraine's air defense shot down two X-59 guided missiles launched by Russian fighter jets, the Ukrainian Air Force said on its Telegram channel.

Russia fired four missiles at Odesa, Andriy Yermak, the head of the presidential office, said on his Telegram channel. Two rockets were shot down by Ukrainian air defense, and two rockets hit the city, he said.

Three people were wounded, and a three-story building on the complex of a monastery was damaged, Yermak said.

Three people were killed, and four were wounded as a result of Russian shelling in the Donetsk region, the Ukrainian Office of the Prosecutor General reported on Facebook.

The Patriot missile training for Ukrainian troops at Fort Sill, Oklahoma, is wrapping up soon, an Army spokesman said Tuesday.

Sixty-five Ukrainian soldiers have been training at Fort Sill since mid-January in an expedited training cycle on using the Patriots -- training that typically can last up to a year.

The Ukrainians will depart the Army post in the coming days for Europe, where they will receive additional training, before heading back to Ukraine "in the coming weeks," Col. Marty O’Donnell of U.S. Army Europe/Africa told ABC News.

"In Europe, the Ukrainians training here will meet up with Ukrainians training in Europe, and with U.S., German, and Dutch equipment donations to validate the systems and ensure interoperability," O'Donnell said.

The United States is going to speed up the manufacture and delivery of the 31 Abrams tanks President Joe Biden approved sending to Ukraine, a U.S. official confirmed Tuesday.

Instead of making new tanks from scratch, the Department of Defense will now refurbish the hulls of several older models that will be equipped with more modern equipment, according to the official.

The new delivery target date is fall 2023, the official said; previously the anticipated delivery time was believed to be mid-2024.

National Security Council spokesperson John Kirby hinted at the accelerated timeline on Tuesday.

"We're working on that," Kirby said on MSNBC. "There's some changes that you can make to the process to sort of speed that up."
