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.

Secretary of State Antony Blinken has determined that Wall Street Journalist reporter Evan Gershkovich is being wrongfully detained by Russia, according to a statement released Monday afternoon.

Two Americans are now considered to be wrongfully detained by Russia -- Gershkovich and Paul Whelan.

Gershkovich’s case will now be transferred to the Office of the Special Envoy for Hostage Affairs, the U.S. government’s top hostage negotiator.

Gershkovich, a 31-year-old New Jersey native who has lived and worked in Moscow as an accredited journalist for the last six years, was in a restaurant in Yekaterinburg on March 29 when Russia's Federal Security Service arrested him on espionage charges that the Wall Street Journal, his colleagues and the U.S. government have said are absurd.
