The U.S. State Department reportedly confirmed the death of Chilean-American blogger Gonzalo Lira, who had been imprisoned in Ukraine for criticizing the country's government.

"We can confirm the death of a U.S. citizen in Ukraine. We offer our sincerest condolences to the family on their loss," a State Department official told Russian news agency TASS. 

"We stand ready to provide all appropriate consular assistance. Out of respect to the family during this difficult time, we have no further comment," the official added.

The statement came after Tucker Carlson announced his death, per Lira's father. 

"Gonzalo Lira, Sr. says his son has died at 55 in a Ukrainian prison, where he was being held for the crime of criticizing the Zelensky and Biden governments," Carlson wrote, linking to his story about the commentator last month. "Gonzalo Lira was an American citizen, but the Biden administration clearly supported his imprisonment and torture. Several weeks ago we spoke to his father, who predicted his son would be killed."
