Context: Robert Seldon Lady (born February 2, 1954 in Tegucigalpa, Honduras; nicknamed "Mister Bob") is a United States agent convicted of kidnapping in Italy for his role in the CIA's abduction of Egyptian cleric Hassan Mustafa Osama Nasr in February 2003, while Lady was CIA station chief in Milan. The Egyptian Islamic Jihad (Arabic: الجهاد الإسلامي المصري‎ ‎ ) (EIJ), formerly called simply Islamic Jihad (الجهاد الإسلامي and "Liberation Army for Holy Sites"), originally referred to as al-Jihad, and then the Jihad Group, or the Jihad Organization, is an Egyptian Islamist terrorist group active since the late 1970s.  It is under worldwide embargo by the United Nations as an affiliate of al-Qaeda.  It is also banned by several individual governments worldwide.  The group is a Proscribed Organisation in the United Kingdom under the Terrorism Act 2000. Syon House, and its 200-acre (80 hectare) park, Syon Park, is in west London, historically within the parish of Isleworth, in the county of Middlesex.  It belongs to the Duke of Northumberland and is now his family's London residence.  The family's traditional central London residence had been Northumberland House, now demolished.  The eclectic interior of Syon House was designed by the architect Robert Adam in the 1760s. Hassan Mustafa Osama Nasr (Arabic: حسن مصطفى أسامة نصر‎ ‎ "Ḥassan Muṣṭafā Usāmah Naṣr") (born 18 March 1963), also known as Abu Omar, is an Egyptian cleric.  In 2003, he was living in Milan, Italy, from where he was kidnapped and tortured in Egypt.  This ""Imam rapito affair"" prompted a series of investigations in Italy, culminating in the criminal convictions (in absentia) of 22 CIA operatives, a U.S. Air Force colonel, and two Italian accomplices, as well as Nasr, himself. Lynne Irene Stewart (October 8, 1939 – March 7, 2017) was an American defense attorney who was known for representing controversial, poor, and often unpopular defendants.  She was convicted on charges of conspiracy and providing material support to terrorists in 2005, and sentenced to 28 months in prison.  Her felony conviction led to her being automatically disbarred.  She was convicted of helping pass messages from her client, Sheikh Omar Abdel-Rahman, an Egyptian cleric convicted of planning terror attacks, to his followers in al-Gama'a al-Islamiyya, an organization designated as a Foreign Terrorist Organization by the United States Secretary of State. Mamdouh Ismail (Arabic: ممدوح إسماعيل‎ ‎ ) is an Egyptian defence attorney and a former member of "the Jihad group" (later called Egyptian Islamic Jihad), who since the 1980s has represented various Egyptians accused of terrorism offences in Egypt.  He was arrested himself on 29 March 2007 and is now accused of complicity in an "Egyptian project" of al-Qaeda, taking his orders from Ayman al-Zawahiri via Muhammad Khalil al-Hukaymah (al-Qaeda propaganda chief) and Hani al-Sibai (publicist for Egyptian Islamic Jihad).  All three—Ismail, al-Sibai, and al-Hukaymah -- deny that charge.  Ismail is also charged with incitement.  As of late 2011, he was a member of the Authenticity Party. Guido Salvini (born 1954) is an Italian judge, based in Milan.  He issued European arrest warrants in 2005 against approximatively 20 CIA agents accused of having taken part in the abduction of Abu Omar, the Egyptian cleric in Milan in 2003.  The case is known in Italy as the "Imam Rapito affair".  Before that, Guido Salvini was in charge of investigations, since July 1988, concerning Italy's strategy of tension during the 1970s. Encyclopedia of Afghan Jihad (aka Encyclopedia of the Afghani Jihad or Encyclopedia of Afghan Terrorism) is a manual of Jihad in eleven volumes, detailing how to make and use explosives and firearms, how to plan and carry out assassinations and other terrorist acts, and much more.  It was found in the London residence of Islamic cleric Sheikh Abu Hamza al-Masri in May 2004.  During al-Masri's trial, the prosecution referred to the literature as a "blueprint for terror". Mustafa Kamel Mustafa (Arabic: مصطفى كامل مصطفى‎ ‎ ; born 15 April 1958), also known as Abu Hamza al-Masri ( أبو حمزة المصري , "Abū Ḥamzah al-Maṣrī" – literally, the Egyptian father of Hamza), the Hook Hand or simply Abu Hamza, is an Egyptian cleric who was the imam of Finsbury Park Mosque in London, England, where he preached Islamic fundamentalism and militant Islamism. Mohamed Yousry is an interpreter and translator who was appointed by the court to assist in the trial of Sheikh Omar Abdel Rahman, the blind Egyptian cleric who was convicted in 1996 of plotting terrorist attacks against various sites in the New York City area.  On February 10, 2005, Yousry was indicted in the United States District Court, Southern District of New York, along with attorney Lynne Stewart and Ahmed Abdel Sattar, of conspiring to provide, and providing material support to terrorism and conspiring to defraud the U.S. government, and was convicted.  Yousry was originally scheduled to be sentenced in September 2006, but he was sentenced on October 16, 2006, to one year and eight months.
