In a Sunday website post, the militant group claimed to have planted the bomb at a security force post close to the university, resulting in the deaths of four police officers and avoiding injuries to passers-by. Representatives of the Egyptian Health Ministry and police force, however, reported that four civilians were wounded.
The group previously claimed responsibility in January for a bomb which killed a bomb disposal officer in the Talbia district in Giza, 20 kilometers southwest of Cairo, and another attack in November which left five policemen wounded.
According to the Tahrir Institute, "Ajnad Misr is the only terrorist group operating exclusively in the Greater Cairo area," and the most active one operating outside the Sinai peninsula, where violence has escalated since the ousting of Egyptian President Mohammed Morsi in July 2013. In contrast to Sinai jihadi groups, says the think-tank, Ajnad Misr "does not fully insist on the establishment of an Islamic caliphate," and employs the language of the January 2011 revolution.
