Iran protesters need same western support as Ukraine, say exiles

Iranian opposition sign open letter calling for tougher measures over regime's actions against protesters

A prominent group of Iranians in exile, human rights activists and families of dual-national political prisoners has called on the west to do more to help Iranians' demands for freedom.

The EU, US and UK have imposed largely symbolic travel bans and asset freezes on a dozen security officials linked to a crackdown on people protesting in Iran after the death in custody of Mahsa Amini in mid-September. The west has not broken off talks with the Iranian regime over the 2015 nuclear deal or downgraded diplomatic relations.
