DUBAI –

At least 16 people have been killed during a week of unrest in Iran, rights groups said on Sunday, as protests over soaring inflation spread across the country, sparking violent clashes between demonstrators and security forces.

Deaths and arrests have been reported through the week both by state media and rights groups, though the figures differ. It has not been possible to independently verify the numbers.

The protests are the ​biggest in three years. Senior figures have struck a softer tone than in some previous bouts of unrest, at a ‍moment of ⁠vulnerability for the Islamic Republic with the economy in tatters and international pressure building.
