Escalation continues

The [British] foreign secretary has condemned the arrest of Britain’s ambassador in Iran during anti-government protests as a “flagrant violation of international law” and said the country was marching towards “pariah status”.

Dominic Raab’s strongly worded statement came after the ambassador, Rob Macaire, was arrested on Saturday during demonstrations near Amirkabir University in Tehran for “inciting” the protesters. He was held for more than an hour on suspicion of organising, provoking and directing radical actions before he was released, the Iranian Tasnim news agency said.

It is understood that Macaire, a distinguished diplomat with 30 years’ experience, had been attending what had been billed as a vigil for the victims of the crash.

However, the event quickly turned into a demonstration, at which point the ambassador left. It was as he was returning to the British embassy that he was arrested, although it is not clear who he was held by.
