US government issues warning as Donald Trump says US will take ‘very strong action’ if Iran hangs protesters

Non-essential French embassy staff have left Iran, two sources with knowledge of the matter told Agence France-Presse. The personnel left on Sunday and Monday, the sources added, without saying how many people had departed. “The protection of our personnel and our citizens is a priority,” a French foreign ministry official told AFP.

Commenting on the protests, the UN high commissioner for human rights Volker Türk said:

This cycle of horrific violence cannot continue. The Iranian people and their demands for fairness, equality and justice must be heard.
