British-Iranian aid worker, Nazanin Zaghari-Ratcliffe lost her appeal against a new prison sentence in Iran on Saturday, after being jailed for five years on security offenses.
That's according to quotes by her lawyer that were reported in an Iranian news website.
In April, an Iranian court sentenced Zaghari-Ratcliffe to the new term on charges of propaganda against Iran's ruling system.
That comes just a month after finishing her prior five-year sentence.
Her lawyer told an Iranian website that a hearing was not held.
Iran's judiciary did not immediately comment on Saturday's decision.
In 2016, Zaghari-Ratcliffe, a project manager with the Thomson Reuters Foundation, was arrested at an airport in the capital Tehran.
She was later convicted of plotting to overthrow the clerical establishment.
Her family and the foundation have repeatedly denied the charges.
The detentions of dozens of dual nationals and foreigners have complicated ties between Iran and several European countries including Germany, France and Britain.
All are parties to Tehran's 2015 nuclear deal with six world powers.
Saturday's decision came as indirect talks between Iran and the U.S. to revive that deal have stalled, after the election of hardline cleric Ebrahim Raisi as president.
