The latest news on these activists comes from Human Right Watch:

Iranian authorities are holding at least eight activists and journalists arrested during a Labor Day protest on May 1, 2019, Human Rights Watch said today. The authorities should immediately and unconditionally release all those detained for exercising their rights to peaceful assembly.

Radio Farda, the United States-funded news agency, reported on May 1 that the authorities had arrested more than 35 people in a demonstration in front of Iran’s parliament that was organized by 20 independent local labor rights organizations. While the authorities released several of those detained, including Reza Shahabi, a prominent labor activist, security forces continue to detain others in Evin prison. They include the activists Neda Naji, Atefeh Rangriz, Nahid Khodajoo, Nasrin Javadi, and Farhad Sheikhi,Hassan Saeedi, and two journalists arrested at the protest, Marizeh Amiri and Keyvan Samimi.

“Instead of commemorating May Day by allowing labor activists to peacefully raise their demands to parliament, Iranian authorities arrested them and put them in jail,” said Michael Page, deputy Middle East director at Human Rights Watch. “While Iranian authorities regularly highlight the potentially negative impact of US sanctions on Iranian civilians, they brook almost zero domestic criticism of their own economic policies by labor activists.”
