After the August missile strikes, diplomatic options to press the Taliban seemed no more promising than military options. The United States had issued a formal warning to the Taliban, and also to Sudan, that they would be held directly responsible for any attacks on Americans, wherever they occurred, carried out by the Bin Laden network as long as they continued to provide sanctuary to it. For a brief moment, it had seemed as if the August strikes might have shocked the Taliban into thinking of giving up Bin Laden. On August 22, the reclusive Mullah Omar told a working-level State Department official that the strikes were counterproductive but added that he would be open to a dialogue with the United States on Bin Laden's presence in Afghanistan. Meeting in Islamabad with William Milam, the U.S. ambassador to Pakistan, Taliban delegates said it was against their culture to expel someone seeking sanctuary but asked what would happen to Bin Laden should he be sent to Saudi Arabia. Yet in September 1998, when the Saudi emissary, Prince Turki, asked Mullah Omar whether he would keep his earlier promise to expel Bin Laden, the Taliban leader said no. Both sides shouted at each other, with Mullah Omar denouncing the Saudi government. Riyadh then suspended its diplomatic relations with the Taliban regime. (Saudi Arabia, Pakistan, and the United Arab Emirates were the only countries that recognized the Taliban as the legitimate government of Afghanistan.) Crown Prince Abdullah told President Clinton and Vice President Gore about this when he visited Washington in late September. His account confirmed reports that the U.S. government had received independently. Other efforts with the Saudi government centered on improving intelligence sharing and permitting U.S. agents to interrogate prisoners in Saudi custody. The history of such cooperation in 1997 and 1998 had been strained. Several officials told us, in particular, that the United States could not get direct access to an important al Qaeda financial official, Madani al Tayyib, who had been detained by the Saudi government in 1997.67Though U.S. officials repeatedly raised the issue, the Saudis provided limited information. In his September 1998 meeting with Crown Prince Abdullah, Vice President Gore, while thanking the Saudi government for their responsiveness, renewed the request for direct U.S. access to Tayyib. The United States never obtained this access. An NSC staff-led working group on terrorist finances asked the CIA in November 1998 to push again for access to Tayyib and to see "if it is possible to elaborate further on the ties between Usama bin Ladin and prominent individuals in Saudi Arabia, including especially the Bin Laden family." One result was two NSC-led interagency trips to Persian Gulf states in 1999 and 2000. During these trips the NSC, Treasury, and intelligence representatives spoke with Saudi officials, and later interviewed members of the Bin Laden family, about Usama's inheritance. <sep>Who was the US trying to contact during strained Saudi Relations in 1997, when they were denied the opportunity to question detainees?<sep>Bin laden

Tuesday, September 11, 2001, dawned temperate and nearly cloudless in the eastern United States. Millions of men and women readied themselves for work. Some made their way to the Twin Towers, the signature structures of the World Trade Center complex in New York City. Others went to Arlington, Virginia, to the Pentagon. Across the Potomac River, the United States Congress was back in session. At the other end of Pennsylvania Avenue, people began to line up for a White House tour. In Sarasota, Florida, President George W. Bush went for an early morning run. For those heading to an airport, weather conditions could not have been better for a safe and pleasant journey. Among the travelers were Mohamed Atta and Abdul Aziz al Omari, who arrived at the airport in Portland, Maine. Boston: American 11 and United 175. Atta and Omari boarded a 6:00 A.M. flight from Portland to Boston's Logan International Airport. When he checked in for his flight to Boston, Atta was selected by a computerized prescreening system known as CAPPS (Computer Assisted Passenger Prescreening System), created to identify passengers who should be subject to special security measures. Under security rules in place at the time, the only consequence of Atta's selection by CAPPS was that his checked bags were held off the plane until it was confirmed that he had boarded the aircraft. This did not hinder Atta's plans. Atta and Omari arrived in Boston at 6:45. Seven minutes later, Atta apparently took a call from Marwan al Shehhi, a longtime colleague who was at another terminal at Logan Airport. They spoke for three minutes. It would be their final conversation. <sep>At what time did Atta take a phone call from Marwan al Shehhi?<sep>6:07

The modern Republic of Turkey dates only from 1923, but the history of the land within its borders stretches back to the dawn of humanity. Widespread finds of Stone Age implements in cave excavations show that Anatolia was already inhabited during the Middle of the Palaeolithic period (about 200,000 to 40,000 years ago). By Neolithic times, organized communities had arisen, such as the one at Catalhoyuk, near Konya, Turkey's most important prehistoric site. This town, which flourished between 6500 and 5500 b.c. , had flat-roofed houses of mud and timber decorated with wall-paintings, some of which show patterns that still appear on Anatolian kilims. The advent of the Bronze Age (about 3200 b.c. ), and the spread of city-states ruled by kings, is marked by the appearance of royal tombs containing bronze objects in such places as Troy in the west, and Alacahoyuk near Ankara. Around this time the Sumerian civilization living in Mesopotamia (the region between the Tigris and Euphrates rivers in present-day Iraq) founded and developed the cuneiform script, the world's oldest form of writing on record. The technique was introduced by Assyrian traders 1,000 years later into Anatolia, where it was quickly adopted by the indigenous Hatti people, who, at this point, had already reached an advanced state of civilization. The Hittites: The capital of the Hatti was Kanesh (modern Kultepe, near Kayseri). Cuneiform tablets found here record the arrival in Anatolia of warlike invaders around the second millennium b.c. Their origins remain a mystery (their written language was finally deciphered in 1915), but they came from the direction of the Caucasus mountains, spreading destruction and disorder throughout Anatolia. It was two hundred years before they were firmly entrenched in their newly conquered empire. The newcomers were the Hittites, and their domination of Anatolia can be divided into three distinct periods: the Old Kingdom (c. 16001450 b.c. ), then the New or Empire Period (c. 14501200 b.c. ), and the Late Hittite Period (c. <sep>How could one describe Catalhoyuk, near Konya?<sep>It flourished between 6500 and 5500 b.c
