Example Input: Bin Laden began delivering diatribes against the United States before he left Saudi Arabia. He continued to do so after he arrived in Sudan. In early 1992, the al Qaeda leadership issued a fatwa calling for jihad against the Western "occupation" of Islamic lands. Specifically singling out U.S. forces for attack, the language resembled that which would appear in Bin Laden's public fatwa in August 1996. In ensuing weeks, Bin Laden delivered an often-repeated lecture on the need to cut off "the head of the snake." By this time, Bin Laden was well-known and a senior figure among Islamist extremists, especially those in Egypt, the Arabian Peninsula, and the Afghanistan-Pakistan border region. Still, he was just one among many diverse terrorist barons. Some of Bin Laden's close comrades were more peers than subordinates. For example, Usama Asmurai, also known as Wali Khan, worked with Bin Laden in the early 1980s and helped him in the Philippines and in Tajikistan. The Egyptian spiritual guide based in New Jersey, the Blind Sheikh, whom Bin Laden admired, was also in the network. Among sympathetic peers in Afghanistan were a few of the warlords still fighting for power and Abu Zubaydah, who helped operate a popular terrorist training camp near the border with Pakistan. There were also rootless but experienced operatives, such as Ramzi Yousef and Khalid Sheikh Mohammed, who-though not necessarily formal members of someone else's organization-were traveling around the world and joining in projects that were supported by or linked to Bin Laden, the Blind Sheikh, or their associates. In now analyzing the terrorist programs carried out by members of this network, it would be misleading to apply the label "al Qaeda operations" too often in these early years. Yet it would also be misleading to ignore the significance of these connections. And in this network, Bin Laden's agenda stood out. While his allied Islamist groups were focused on local battles, such as those in Egypt, Algeria, Bosnia, or Chechnya, Bin Laden concentrated on attacking the "far enemy"-the United States. After U.S. troops deployed to Somalia in late 1992, al Qaeda leaders formulated a fatwa demanding their eviction. In December, bombs exploded at two hotels in Aden where U.S. troops routinely stopped en route to Somalia, killing two, but no Americans. <sep>What was the names and locations of two peers of bin Ladin?<sep>Blind Sheik - New Jersey

Example Input: During this time, Alexander adopted some elements of Persian dress and customs at his court, notably the custom of proskynesis, either a symbolic kissing of the hand, or prostration on the ground, that Persians showed to their social superiors. The Greeks regarded the gesture as the province of deities and believed that Alexander meant to deify himself by requiring it. This cost him the sympathies of many of his countrymen, and he eventually abandoned it. A plot against his life was revealed, and one of his officers, Philotas, was executed for failing to alert Alexander. The death of the son necessitated the death of the father, and thus Parmenion, who had been charged with guarding the treasury at Ecbatana, was assassinated at Alexander's command, to prevent attempts at vengeance. Most infamously, Alexander personally killed the man who had saved his life at Granicus, Cleitus the Black, during a violent drunken altercation at Maracanda (modern day Samarkand in Uzbekistan), in which Cleitus accused Alexander of several judgemental mistakes and most especially, of having forgotten the Macedonian ways in favour of a corrupt oriental lifestyle. Later, in the Central Asian campaign, a second plot against his life was revealed, this one instigated by his own royal pages. His official historian, Callisthenes of Olynthus, was implicated in the plot; however, historians have yet to reach a consensus regarding this involvement. Callisthenes had fallen out of favor by leading the opposition to the attempt to introduce proskynesis. <sep>Who lost their lives when a plot against Alexander's life was revealed?<sep>Cleitus the Black
