On Thursday, 7 April 2005, a suicide bomber detonated an explosive device on Sharia al-Moski in Islamic Cairo, near the al-Hussein Mosque and Khan el-Khalili, a major souq popular with tourists and Egyptians alike.
Egyptian police identified the bomber as Muhammad Sobhi Ali Jidan, originally from Qalyubia Governorate in northern Egypt, but then living in the north Cairo district of Shobra.
The first of a number of attacks on Saturday, 30 April took place at 15h15 Egypt summer time (12h15 UTC) in a city bus station located in a 300-metre-wide concourse between the Ramses Hilton Hotel and the Egyptian Museum near Cairo's main traffic intersection.
Ehab Yousri Yassin, an Egyptian man suspected of involvement in the 7 April attack, was being pursued along the Sixth of October Bridge, a flyover leading into centre of Cairo from the River Nile island of Gezira.
Approximately two hours later the same day, two veiled females armed with guns opened fire on a tourist bus in the neighbourhood known as Islamic Cairo, not far from the Citadel.
