The Iranian Islamic regime has been seriously challenged since the start of public protests last September. The government has sought to contain and suppress the protesters – even resorting to executions – but has been unable to stop them.
There are continuing reports of mass demonstrations in various parts of the country, including in the capital Tehran and other major cities in recent weeks.
The European Union last week placed new sanctions on Iranian individuals and entities, but stopped short of labelling the Revolutionary Guards a terrorist group. Australia has also imposed new sanctions on Iranian officials, but critics have said it is not sufficient.
