Security and police forces violently attacked Iranian workers as they gathered in Laleh Park in Tehran to observe International Workers’ Day on May 1st, the International Campaign for Human Rights in Iran reported. The demonstration had been called by ten independent labor organizations. According to information received by the Campaign more than 100 persons were arrested, and citizens not participating in the attempted May Day observance were among those beaten. “These brutal and deplorable attacks are emblematic of the Iranian government’s utter contempt for workers and for the state’s international obligations to protect worker’s rights,” stated Hadi Ghaemi, spokesperson for the Campaign.
