The National Anti-Coup Alliance in Egypt has denounced the deadly explosion that rocked a police headquarters in the Nile Delta city of Mansoura early on Tuesday morning. The attack claimed the lives of at least 13 Egyptians, wounding more than 130.
The blast took place in front of the security Directorate of the Daqahleya Governorate, and caused massive damage to the buildings.
Since the military coup that deposed the democratically elected President Mohammed Morsi on 3 July, Egypt's security forces have launched a massive crackdown on his supporters. The worsening political crisis has been accompanied by an increase in violence, especially in the north of Egypt.
The Freedom and Justice Gate carried the National Alliance's statement, which expressed deep concern for the devastated families of the victims. The group put responsibility for the deaths on Egypt's "corrupted security staff", who they say "spread violence in the country".
The National Alliance also affirmed that: "The blood of Egyptians is a taboo and thus outlawed."
The group warned of plans to escalate the violence in Egypt after Naguib Sawiris, a prominent Coptic Egyptian businessman, threatened to use force against nonviolent anti-coup protesters.
Meanwhile, the Muslim Brotherhood also issued a statement condemning Tuesday's attack "in the strongest possible terms". The statement noted that the "Muslim Brotherhood mourns the loss of life of all of these sons and daughters of Egypt and sends its heartfelt condolences to those injured and the families that have lost loved ones."
Despite the Muslim Brotherhood's denunciation of the violence and the commitment they have repeatedly demonstrated to nonviolent civil protests, according to the MENA state news agency, immediately after the attack interim Prime Minister Hazem Al-Beblawi declared the Muslim Brotherhood to be a terrorist organisation.
