Khan el-Khalili
Mabruk ran al-Jihad operations under the front organisation "Bavari-C". He was a vocal critic of the group's close connections to Osama bin Laden, and criticised its leadership for allowing such a close relationship. In 1995, he was sentenced to death "in absentia" for plotting to bomb the Khan el-Khalili market in Cairo, along with Ahmad Ibrahim al-Sayyid al-Naggar and Adel Abdel Bary.
