Background: The Etruscan civilization () is the modern name given to a powerful and wealthy civilization of ancient Italy in the area corresponding roughly to Tuscany, western Umbria and northern Lazio. As distinguished by its unique language, this civilization endured from before the time of the earliest Etruscan inscriptions (c. 700 BC) until its assimilation into the Roman Republic, beginning in the late 4th century BC with the Roman-Etruscan Wars. Culture that is identifiably Etruscan developed in Italy after about 800 BC, approximately over the range of the preceding Iron Age Villanovan culture. The latter gave way in the 7th century BC to a culture that was influenced by Ancient Greek culture.
Context: The ancient Romans referred to the Etruscans as the Tusci or Etrusci. Their Roman name is the origin of the terms "Tuscany", which refers to their heartland, and "Etruria", which can refer to their wider region. In Attic Greek, the Etruscans were known as Tyrrhenians (Turrenoi, Turrhenoi, earlier Tursenoi Tursenoi), from which the Romans derived the names Tyrrheni, Tyrrhenia (Etruria), and Mare Tyrrhenum (Tyrrhenian Sea), prompting some to associate them with the Teresh (Sea Peoples). The word may also be related to the Hittite Taruisa. The Etruscans called themselves Rasenna, which was syncopated to Rasna or Rasna. The origins of the Etruscans are mostly lost in prehistory, although Greek historians as early as the 5th century BC repeatedly associated the Tyrrhenians (Turrhenoi/Turrenoi, Tursenoi/Tursenoi) with Pelasgians. Thucydides, Herodotus and Strabo all denote Lemnos as settled by Pelasgians whom Thucydides identifies as "belonging to the Tyrrhenians" (to de pleiston Pelasgikon, ton kai Lemnon pote kai Athenas Tursenon), and although both Strabo and Herodotus agree that Tyrrhenus/Tyrsenos, son of Atys, king of Lydia, led the migration, Strabo specifies that it was the Pelasgians of Lemnos and Imbros who followed Tyrrhenus/Tyrsenos to the Italian Peninsula. The Lemnian-Pelasgian link was further manifested by the discovery of the Lemnos Stele, whose inscriptions were written in a language which shows strong structural resemblances to the language of the Tyrrhenians (Etruscans). Dionysius of Halicarnassus records a Pelasgian migration from Thessaly to the Italian peninsula, noting that "the Pelasgi made themselves masters of some of the lands belonging to the Umbri"; Herodotus describes how the Tyrrheni migrated from Lydia to the lands of the Umbri (Ombrikoi). Strabo as well as the Homeric Hymn to Dionysus make mention of the Tyrrhenians as pirates. Pliny the Elder put the Etruscans in the context of the Rhaetian people to the north and wrote in his Natural History (AD 79): Adjoining these the (Alpine) Noricans are the Raeti and Vindelici. All are divided into a number of states. The Raeti are believed to be people of Tuscan race driven out by the Gauls, their leader was named Raetus.

Answer: Strabo as well as the Homeric Hymn to Dionysus make mention of the Tyrrhenians as pirates.

Problem: Background: Khalid Sheikh Mohammed (sometimes also spelled Khalid Shaikh Mohammed; among at least fifty pseudonyms; born March 1, 1964) is an Islamist militant held by the United States at the Guantanamo Bay detention camp under terrorism-related charges. He was named as "the principal architect of the 9/11 attacks" in the 9/11 Commission Report. Sheikh Mohammed was a member of Osama bin Laden's al-Qaeda organization, leading al-Qaeda's propaganda operations from around 1999 until late 2001. He confessed to FBI and CIA agents to a role in many of the most significant terrorist plots over the last twenty years, but his interrogators' use of enhanced interrogation techniques has caused some to question certain aspects of his confessions.
Context: By the time the Bojinka plot was discovered, Mohammed had returned to Qatar and his job as a project engineer at the country's Ministry of Electricity and Water. He traveled in 1995 to Sudan, Yemen, Malaysia, and Brazil to visit elements of the worldwide jihadist community, although no evidence connects him to specific terrorist actions in any of those locations. On his trip to Sudan, he attempted to meet with Osama Bin Laden, who was at the time living there, aided by Sudanese political leader Hassan al-Turabi. After the US asked the Qatari government to arrest Mohammed in January 1996, he fled to Afghanistan, where he renewed his alliance with Abdul Rasul Sayyaf. Later that year, he formed a working relationship with Bin Laden, who had settled there. Bin Laden and his colleagues relocated their operations to Afghanistan at this time. Abu Hafs al-Masri/Mohammed Atef, bin Laden's chief of operations, arranged a meeting between bin Laden and Mohammed in Tora Bora sometime in mid-1996, in which Mohammed outlined a plan that would eventually become the quadruple hijackings of 2001. Bin Laden urged Mohammed to become a full-fledged member of Al Qaeda, but he continued to refuse such a commitment until around early 1999, after the 1998 U.S. embassy bombings in Nairobi and Dar es Salaam. Mohammed moved his family from Iran to Karachi, Pakistan, in 1997. That year, he tried unsuccessfully to join mujahideen leader Ibn al-Khattab in Chechnya, another area of special interest to Mohammed. Unable to travel to Chechnya, he returned to Afghanistan. He ultimately accepted bin Laden's invitation to move to Kandahar and join al-Qaeda as a full-fledged member. Eventually, he became leader of Al Qaeda's media committee.
Question: Did Khalid work with anyone else in his planning?
Answer:
Abu Hafs al-Masri/Mohammed Atef,
