Iranian authorities have detained at least 26 people in the city of Ahwaz and its surroundings in the southwestern province of Khuzestan during the weeks leading up to the April 15 anniversary of a 2005 protest and subsequent crackdown.

The International Campaign for Human Rights in Iran called for the immediate release of all detainees. Between late March and April 16, according to the European Ahwazi Human Rights Organisation (EAHRO), Iranian security and intelligence agents detained 26 activists to prevent the commemoration of the April 15 anniversary.

On 15 April 2005, widespread demonstrations broke out in various neighborhoods of Ahwaz in protest against ethnic discrimination and government policies which lead to substantial dislocation of Arab-Iranians and impoverishment of local communities. At the time, Iranian authorities arrested hundreds of protestors, and since then they have responded to local grievances with a heavy-handed policy of repression, detentions, torture, and even executions of activists.

EAHRO has provided the names of the 25 men and 1 woman detained over the past several weeks:
