A coalition of nineteen Egyptian rights group issued a statement on Saturday denouncing the killing of pro-Morsi female protesters in Mansoura last Friday, calling for immediate investigations.
"We call on the public prosecutor for an immediate and transparent investigation in the incident," read the statement, which demanded that the perpetrators be found quickly and put on trial.
According to the statement, security forces were not present at the scene of clashes until the situation had escalated, despite being called upon by local residents.
"Consequently, [we] assert that the Egyptian government is fully responsible," read the statement, adding that it held the interior ministry and the Daqahlia governorate security directorate specifically responsible.
The rights groups, which included the Cairo Centre for Development and Human Rights, the Nabd Centre for Supporting Democracy and Fighting Corruption, the Regional Centre for Media and Development Studie, the Nile Centre for Media and Legal Studies and the El-Dameer Centre for Human Rights, called on the government to secure peaceful protests throughout governorates and to protect citizens regardless of political affiliation.
At least three women were announced dead by Egypt's health ministry late on Friday after clashes erupted between supporters of deposed president Mohamed Morsi and unknown assailants.
The Muslim Brotherhood claims that four women were killed in the incident. Eight others were reported injured.
Live rounds, birdshot, and knives were used in the attack, according to witnesses who talked to Al-Ahram's Arabic website.
