At least 32 Azeri activists were arrested in the lead-up to an annual July protest at the historic Babak Fort in Iran's East Azerbaijan province against discrimination targeting the ethnic minority. The arrests took place in several citiese, including Tabriz and Ahar in East Azerbaijan and Meshgin Shahr in neighboring Ardabil province, usually following home raids. Security officials contacted a large number of local activists and warned them to not attend the annual ceremony. Dozens more were summoned and threatened with arrest if they attended the ceremony. Babak Fort, also known as the Immortal Castle or Republic Castle, is a mountaintop citadel said to have been the stronghold of Babak Khorramdin, the leader of the Khurramite rebellion who fought the Abbassid caliphate in the ninth century CE. Babak is revered as a national hero by ethnic Azeris and Iranians alike. Azeris, also known as Azarbaijani Turks, have for several years gathered at the citadel on the first weekend in July for the annual ceremony.
