Russia-Ukraine updates: 2 US veterans who joined Ukrainian forces missing

U.S. Defense Secretary Lloyd Austin said meetings like the one on Tuesday with more than 40 NATO allies and other partner nations will now occur monthly.

"To ensure that we continue to build on our progress, we're going to extend this forum beyond today," Austin said during a news conference at Ramstein Air Base in Germany.

"I'm proud to announce that today's gathering will become a monthly contact group on Ukraine's self-defense," he said.

The meetings will focus on strengthening Ukraine's military both in the short and long terms, Austin said.

"The contact group will be a vehicle for nations of good will to intensify our efforts and coordinate our assistance and focus on winning today's fight and the struggles to come," Austin said. "The monthly meetings may be in person, virtual, or mixed."

Austin, who visited Ukraine on Sunday with U.S. Secretary of State Antony Blinken, praised Tuesday's meeting with NATO allies, saying, "We're all coming away with a transparent and shared understanding of a challenge that Ukrainians face."

Austin conveyed a sense of urgency for the international community to help the Ukrainians.

"I applaud all of the countries that have risen, and are rising, to this moment," he said. "But we don’t have any time to waste. The briefings today laid out clearly why the coming weeks will be so crucial for Ukraine. So, we’ve got to move at the speed of war."

Austin thanked Germany for hosting Tuesday's meeting and for offering to send Ukraine 50 Cheetah anti-aircraft systems. He also thanked the United Kingdom for its announcement Monday that it would provide Ukraine additional anti-aircraft capabilities.

"We held an important session today with long-term support for Ukraine’s defenses, including what that will take from our defense industrial bases," Austin said. "That means dealing with the tremendous demand that we’re facing for munitions and weapons platforms, and giving our staunch support to Ukraine while also meeting our own requirements, and those of our allies and partners."

A Soviet-era statue that has stood in the capital of Ukraine since 1982 and once symbolized the friendship between Russia and Ukraine was taken down on Tuesday in response to the war between the two countries.

An ABC News crew was on-hand in Kyiv as a large crane removed the bronze "People's Friendship" statue from its pedestal.

Kyiv Mayor Vitali Klitschko said the statue, a gift from the former Soviet Union, is being dismantled because of the “brutal killing and a desire to destroy our state.”

The statue depicts two workers, a Russian and a Ukrainian, holding up a Soviet Order of Friendship of Peoples. The monument was dedicated in November 1982 to commemorate the 60th anniversary of the USSR and the 1,500th anniversary of Kyiv.

Klitschko said a 164-foot-tall titanium rainbow-shaped arch the statue rested under will remain and be illuminated with the colors of the Ukrainian flag.

The U.S. will "keep moving heaven and earth" to supply aid to Ukraine, Secretary of Defense Lloyd Austin said on Tuesday at a meeting of the Ukraine Security Consultative Group, which includes military representatives from about 40 countries.

“Ukraine clearly believes it can win. And so does everyone here,” Austin said in his opening remarks at Ramstein Air Base in Germany. “I know that we’re all determined to do everything we can to support Ukraine’s needs as the fight evolves.”

Austin said the group would seek to leave with a common understanding of “Ukraine’s near term security requirements, because we’re going to keep moving heaven and earth so that we can meet them.”

Russian forces appeared to be moving to encircle “heavily fortified” Ukrainian positions in the east, the U.K. Ministry of Defense said on Tuesday.

“The city of Kreminna has reportedly fallen and heavy fighting is reported south of Izium, as Russian forces attempt to advance towards the cities of Sloviansk and Kramatorsk from the north and east,” the ministry said in its latest intelligence update.

Ukrainian forces in Zaporizhzhia were preparing for an attack from the south, the ministry said.
