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.
Iran's president warned Wednesday that European soldiers in the Mideast “could be in danger” after three nations challenged Tehran over breaking the limits of its nuclear deal.
