Russia-Ukraine updates: 2 US veterans who joined Ukrainian forces missing
The Americans, Andy Tai Ngoc Huynh and Alexander Drueke, are both from Alabama.
Russian President Vladimir Putin's "special military operation" into neighboring Ukraine began on Feb. 24, with Russian forces invading from Belarus, to the north, and Russia, to the east. Ukrainian troops have offered "stiff resistance," according to U.S. officials.
The Russian military has since launched a full-scale ground offensive in eastern Ukraine's disputed Donbas region, capturing the strategic port city of Mariupol and securing a coastal corridor to the Moscow-annexed Crimean Peninsula.

State Department 'confident' in NATO expansion
As Turkey becomes more vocal about its opposition to Sweden and Finland joining NATO, the State Department said it is still assured of the alliance's unified support for the two prospective members.
State Department spokesperson Ned Price said during a briefing Tuesday that Secretary of State Antony Blinken came away from meetings with NATO allies with a "sense of confidence there was strong consensus for admitting Finland and Sweden into the alliance if they so choose to join, and we're confident we'll be able to preserve that consensus."
Price said that assessment came from what Blinken heard in conversations behind closed doors.
Turkey's president, Recep Tayyip Erdogan, has publicly said that both candidates are untrustworthy because he perceives them as being supportive of groups Ankara views as extremist.
There is speculation that Turkey’s opposition is an attempt to leverage the moment to achieve its own policy goals or concessions from the U.S. Price said Tuesday that Turkey has not made any specific requests.
Price confirmed that Blinken will meet with his Turkish counterpart on the sidelines of the U.N. on Wednesday, adding that "other conversations are ongoing between and among current NATO allies and potential aspirant countries."

Swedish Prime Minister Magdalena Andersson's office announced Sweden and Finland will jointly submit an application for NATO membership on Wednesday, after she met with Finnish President Sauli Niinistö in Stockholm.
"It is a message of strength and a clear signal that we stand united going into the future," Andersson said in a joint press conference with the Finnish president.
The two leaders are set to meet President Joe Biden at the White House on Thursday.
The two countries have stepped away from nonalignment in the wake of Russian's invasion of Ukraine, and fears for their own security.
