In 1993, al-Zawahiri's and Egyptian Islamic Jihad's (EIJ) connection with Iran may have led to a suicide bombing in an attempt on the life of Egyptian Interior Minister Hasan al-Alfi, the man heading the effort to quash the campaign of Islamist killings in Egypt. It failed, as did an attempt to assassinate Egyptian prime minister Atef Sidqi three months later. The bombing of Sidqi's car injured 21 Egyptians and killed a schoolgirl, Shayma Abdel-Halim. It followed two years of killings by another Islamist group, al-Gama'a al-Islamiyya, that had killed over 200 people. Her funeral became a public spectacle, with her coffin carried through the streets of Cairo and crowds shouting, "Terrorism is the enemy of God!" The police arrested 280 more of al-Jihad's members and executed six.
