Eight environmental activists arbitrarily detained in Iran in January and February remain in detention eight months later without clear charges, Human Rights Watch said. The organization called upon Iranian authorities to either immediately release them or charge them with recognizable crimes and produce evidence to justify their continued detention. The detained are all members of the Persian Wildlife Heritage Foundation. The public prosecutor for Tehran told reporters after the arrests that the detained are accused of using environmental projects as a cover to collect classified strategic information. It is unclear what classified information they could potentially collect, as their organization says it only works to conserve and protect Iran's flora and fauna, including the Asiatic cheetah, an endangered species in Iran. Other sources indicated they have been accused of "sowing corruption on earth," a serious charge that carries the risk of execution. (Image via HRW)
