Iranian state-run media say the British ambassador to Iran has left the country after being arrested and briefly detained.
The state-run IRNA news agency says Robert Macaire left after being given prior notice.
The report did not elaborate.
Macaire had been held after attending a candlelight vigil Saturday in Tehran over Iran shooting down a Ukrainian jetliner, killing 176 people.
The vigil quickly turned into an anti-government protests and Macaire left shortly after, only to be arrested by police.
