 The bombings are widely believed to have been revenge for U.S. involvement in the extradition, and alleged torture, of four members of Egyptian Islamic Jihad (EIJ) who had been arrested in Albania for an alleged series of murders in Egypt in the two months prior to the attacks.Between June and July, Ahmad Isma'il 'Uthman Saleh, Ahmad Ibrahim al-Sayyid al-Naggar, Shawqi Salama Mustafa Atiya and Mohamed Hassan Tita were all renditioned from Albania to Egypt, with the co-operation of the United States; the four men were accused of participating in the assassination of Rifaat el-Mahgoub, as well as a later plot against the Khan el-Khalili market in Cairo.The following month, a communique was issued warning the United States that a "response" was being prepared to "repay" them for their interference.
