Security services questioned more people as part of their search for Cairo bombers. So far, though, no accused have been referred to the Prosecution. A French tourist was killed during last week's attack in el-Hussein area, while others were wounded. The search has been expanded in coordination with the general department of the State Security Investigations, the security services and Cairo Investigations Department. Patrols have been sent to several shantytowns across Cairo, Giza and Qalyubia, while houses in popular areas have been searched. Meanwhile, security services in the capital, led by Major General Ismail el-Shaer, First Assistant Interior Minister, have questioned and closely examined cook Abdel Rahman Taher, the person charged with stabbing a US tourist. His personal relationships are also being examined to see whether he has something to do with the explosion or not. Meanwhile, he is having surgery on his shoulder at el-Hussein hospital, as doctors are treating his self-inflicted injuries to his leg. El-Gamaliya Prosecution has decided to keep him in custody for four days in hospital and charged him with attempted murder. It has emerged that the accused used a 30-cm knife hidden in a bunch of press clippings. Eye witnesses said the accused stabbed the US tourist three times, the first while he was getting out of the tunnel, the second in al-Azhar Street, and the third in front of al-Azhar University. They also said that every time he stabbed him, the accused said "God is great" and "You're the cause of the devastation in Gaza". The 51-year-old victim said that he worked as a teacher at the American School of Alexandria and that he was taken aback when a slim person – he could not see his face, though - tried to assault him with a knife.
