Mr. Rezaian’s lawyer, Leila Ahsan, told The Associated Press that she had not been given any information about the sentencing — or even the verdict.

Mr. Rezaian’s brother, Ali, called him “an innocent man and a well-respected journalist,” in a statement on Sunday. “As our family gathers for Thanksgiving, we remain hopeful that Jason will soon be reunited with us.”

Mr. Rezaian, 39, a California native and dual citizen of the United States and Iran, was The Post’s bureau chief in Tehran in July 2014 when he was arrested. He was charged with spying on Iran’s nuclear program and gathering information about violations of international sanctions against Iran.

“He began to identify individuals and companies that violated sanctions and were cooperating with Iran,” an Iranian television station said on its website. “The information that Rezaian gave to the Americans had led many Iranian and international businessmen and companies to be included in America’s sanctions list.”

He was convicted in October after a trial closed to the public.

Mr. Rezaian has been held at Evin Prison in Tehran. Last December, Ali Rezaian said that his brother had had health problems while in custody, including high blood pressure and back pain.
