Iran has vowed it will respond to new sanctions imposed by the European Union and Britain over Tehran's handling of months-long protests triggered by the death in custody of Mahsa Amini.
The EU and Britain on Monday imposed a further round of sanctions on Iran, which has been rocked by protests since the September death of Amini, a 22-year-old Iranian Kurd who was arrested for allegedly breaching the country's strict dress code for women.
