A rights organization has denounced the recent strong-arm crackdown by Egypt’s military-backed government on peaceful protesters that killed at least six people, Press TV reports.

In a Sunday statement, the UK-based Arab Organization for Human Rights (AOHR) condemned the Egyptian government for its crackdown on a peaceful rally on Friday on the occasion of Eid al-Fitr marking the end of the fasting month of Ramadan.

The statement also censured the “silence of the international community” toward the Egyptian government’s use of “deadly force” against peaceful gatherings, describing it as a “green light” to Egyptian authorities to kill opposition activists.

The AOHR further called for a credible investigation into the government’s killing of Muslim Brotherhood members and supporters since the July 2013 overthrow of former President Mohamed Morsi by then army chief and current President Abdel Fattah el-Sisi.

More than 1,400 people were reportedly killed and 16,000 others detained in the crackdown on Morsi’s supporters since his ouster.
