A group called Soldiers of Egypt claimed responsibility for eight bombings since last November until April 2014, including the bombings of Cairo University, and targeting two police checkpoints on the 26 of July corridor and al-Sawah area.
A video attributed to the Soldiers of Egypt on YouTube said the operations of the group are dedicated "to every mother who lost her children, or whose children were subjected to imprisonment at the hands of the criminal authorities."
The video contained scenes from Cairo University bombing, the 25 January revolution, the dispersal of Rabaa and al-Nahda ait-ins, beside other scenes for human rights violations by the police.
The video stressed the group would continue its retaliatory operations againt the security authorities.
