Input: (CNN) -- Jo-Wilfried Tsonga ended Roger Federer's hopes of winning a record-equaling seventh Wimbledon title on Wednesday as the French 12th seed staged a stunning fightback to reach the semifinals. Federer appeared to be cruising into the last four after winning the first two sets, but Tsonga inflicted the Swiss world No. 3's first defeat from that vantage point in 179 grand slam matches. It was only the third time in the 29-year-old's glittering career that the 16-time grand slam champion had surrendered a two-set lead. Tsonga, ranked 19th in the world, triumphed 3-6 6-7 (3-7) 6-4 6-4 6-4 on Centre Court, serving out to love as he earned a clash with second seed Novak Djokovic. The Serbian, who beat Tsonga in the 2008 Australian Open final, ended the dream run of Australian 18-year-old Bernard Tomic. Tsonga defeated Federer for just the second time in six meetings, their first on grass. "It was amazing. I played unbelievable. It's never easy to come back against Roger. I'm so happy, it's crazy," the 26-year-old told reporters after reaching the semifinals at Wimbledon for the first time. "He's the biggest champion in the sport. He has achieved so much and is the best player in the world. To be two sets down and come back was unbelievable. I served really well. Against Djokovic I will have to come out and do the same again." Federer has now lost in the quarterfinals two years in a row, being beaten by eventual runner-up Tomas Berdych in 2010. "Jo played great. Really from start to finish I don't remember seeing a break point after I broke him in the first game," Federer said.

Input: A handful of Bronze Age relics has fostered an assumption that prehistoric settlers inhabited Ibiza thousands of years ago. Greater evidence of such a people is found on Mallorca and Menorca than on Ibiza, but one of the Balearics' most important sites is actually on the island of Formentera, where the megalithic monument/tomb of Ca Na Costa has been dated to 2000 b.c. Ibiza's key location between Africa and ancient Iberia made it a convenient stopover for Mediterranean seafarers, such as the Phoenician traders, who called the island Ibosim. The Greeks dubbed it Ebysos, the Romans called it Ebusus, and the Moors, Yebisah. The Carthaginians: A detailed history of the island doesn't begin until it became a colony of Carthage in the 7th century b.c. . The Carthaginians originally came from the area comprising present-day Lebanon, and from their bases in North Africa and what's now Spain, they challenged the Roman Empire for domination of the Mediterranean region. Their interest in Ibiza lay partly in its vast salt flats, which to this day remain the source of a profitable industry. They capitalized on the natural resources by using the salt to cure fish, which they exported to their home country. The Carthaginians also carried out lead mining and continued to be of significance up until this century. It is believed that the lead pellets which were used by the Carthaginian general Hannibal were made on Ibiza. The Carthaginians also considered the island a holy place, and here in great splendour they buried thousands of their citizens in a huge necropolis on the Puig des Molins (Hill of the Windmills) below the Dalt Vila (Old Town) of Ibiza. Under the gnarled olive trees archaeologists have uncovered a treasure trove of statues, jewellery, pitchers, tools, and coins, which are now displayed in the town's two archaeological museums. The Romans never really infiltrated Ibiza, and even after the defeat of Hannibal in 202 b.c. during the Second Punic War their influence was restrained. Only with the fall of Carthage in 146 b.c. did they manage to make inroads, but, as local historians stress, Ibiza was neither conquered nor annexed by Rome, but confederated, retaining remarkable autonomy. For centuries to come the old Carthaginian traditions were allowed to continue on Ibiza alongside the new Roman way of life.

Input: Zakariya Essabar, a Moroccan citizen, moved to Germany in February 1997 and to Hamburg in 1998, where he studied medical technology. Soon after moving to Hamburg, Essabar met Binalshibh and the others through a Turkish mosque. Essabar turned extremist fairly suddenly, probably in 1999, and reportedly pressured one acquaintance with physical force to become more religious, grow a beard, and compel his wife to convert to Islam. Essabar's parents were said to have made repeated but unsuccessful efforts to sway him from this lifestyle. Shortly before the 9/11 attacks, he would travel to Afghanistan to communicate the date for the attacks to the al Qaeda leadership. Mounir el Motassadeq, another Moroccan, came to Germany in 1993, moving to Hamburg two years later to study electrical engineering at theTechnical University. A witness has recalled Motassadeq saying that he would kill his entire family if his religious beliefs demanded it. One of Motassadeq's roommates recalls him referring to Hitler as a "good man" and organizing film sessions that included speeches by Bin Laden. Motassadeq would help conceal the Hamburg group's trip to Afghanistan in late 1999. Abdelghani Mzoudi, also a Moroccan, arrived in Germany in the summer of 1993, after completing university courses in physics and chemistry. Mzoudi studied in Dortmund, Bochum, and Muenster before moving to Hamburg in 1995. Mzoudi described himself as a weak Muslim when he was home in Morocco, but much more devout when he was back in Hamburg. In April 1996, Mzoudi and Motassadeq witnessed the execution of Atta's will. During the course of 1999, Atta and his group became ever more extreme and secretive, speaking only in Arabic to conceal the content of their conversations. 87 When the four core members of the Hamburg cell left Germany to journey to Afghanistan late that year, it seems unlikely that they already knew about the planes operation; no evidence connects them to al Qaeda before that time. Witnesses have attested, however, that their pronouncements reflected ample predisposition toward taking some action against the United States. In short, they fit the bill for Bin Laden, Atef, and KSM. Going to Afghanistan The available evidence indicates that in 1999, Atta, Binalshibh, Shehhi, and Jarrah decided to fight in Chechnya against the Russians.
