A 26-year-old U.S. Marine Corps veteran was killed in a mortar strike last month in Ukraine while working to evacuate civilians, his family confirmed to ABC News this week.

Cooper Andrews died on April 19 in the Bakhmut area, his cousin Willow Pastard, who is speaking on his family's behalf, told ABC News.

The State Department announced Monday that an American citizen died in Ukraine, though did not provide more details or an identity "out of respect for the family's privacy during this difficult time."

"We are in touch with the family and providing all possible consular assistance," a spokesperson for the agency said in a statement.

At least nine deaths of U.S. citizens who have volunteered to fight in Ukraine have been officially reported since the war began last year, according to the State Department.

After some missed calls, President Joe Biden finally connected with the parents of Wall Street Journal reporter Evan Gershkovich, White House press secretary Karine Jean-Pierre confirmed Tuesday.

"He felt it was really important to connect with Evan's family," she told reporters on Air Force One as the president travels to Ireland.

Meanwhile, National Security Council spokesperson John Kirby said Gershkovich's detention is "pretty fresh" and officials are still trying to get consular access to Gershkovich, which they have not been able to do.

He would not get into any specific conversations the U.S. is having with Russians about releasing Gershkovich or if a prisoner swap is a possibility.

"I just want to make a couple of things clear that is, the determination of wrongful detention, it doesn't start the clock necessarily on communicating with the Russians about getting him released," Kirby said. "We're very early in this process here and I certainly, I think you can understand why I wouldn't talk about any discussions we might be having with the Russians about his release or Paul [Whelan]'s release. We certainly wouldn't do that."

Kirby said the administration is "certainly having discussions about what we can do to get him released."

"I don't want to go into details about these internal deliberations, having things out in the public sphere viscerally might actually make it harder to get Evan and Paul home, and that's what we're focused on," Kirby said.
