Jason Rezaian, a Washington Post reporter with dual American-Iranian citizenship who's been jailed in Tehran for more than 445 days, has been convicted of several charges, including espionage.
It's not entirely clear what all his convictions are, NBC News reported.
Iran's court only said a "ruling" had been reached in the espionage trial, and a conviction concluded, but did not elaborate.

Washington Post executive editor Martin Baron was quick to react, calling the conviction an "outrageous injustice" and vowing to work with Rezaian's family and attorney to appeal, NBC News reported.
"Iran has behaved unconscionably throughout this case, but never more so than with this indefensible decision by a Revolutionary Court to convict an innocent journalist of serious crimes after a proceeding that unfolded in secret, with no evidence whatsoever of any wrongdoing," he said in a statement. "For now, no sentence has been announced."
Rezaian, who's been jailed longer than the Americans in the 1979 Iranian hostage crisis, was arrested in mid-2014 in his home in Tehran, along with his wife. She's since been released. But Rezaian was charged with espionage and several other crimes.

His family put out a statement saying the failure of Iran to release any more information about the actual verdict and sentence "follows an unconscionable pattern by Iranian authorities of silence, obfuscation, delay and a total lack of adherence to international law, as well as Iranian law," CNN reported.
