QUES: Washington (CNN) -- The U.S. Food and Drug Administration announced Wednesday that laboratory tests on popular smoking devices known as electronic cigarettes have found they contain carcinogens and other toxic chemicals dangerous to humans. E-cigarettes are battery-operated and contain cartridges filled with nicotine and other chemicals. Known as "e-cigarettes," the devices are battery-operated and contain cartridges filled with nicotine and other chemicals, spiced with flavors such as chocolate, cola or bubble gum. While manufacturers tout e-cigarettes as a "healthy way" to smoke, federal health officials say the devices turn nicotine, which is highly addictive, and other chemicals into a vapor that is inhaled by the user. "The FDA is concerned about the safety of these products and how they are marketed to the public," said Dr. Margaret A. Hamburg, commissioner of the FDA. CNN contacted Florida-based Smoking Everywhere, one of the largest manufacturers of e-cigarettes, after the FDA announcement, and a spokeswoman said the company had no comment. Because e-cigarettes have not been submitted to the FDA for evaluation or approval, the agency had no way of knowing the levels of nicotine or the amounts or kinds of other chemicals that the various brands of these products deliver to the user. That is why the FDA began to test them. The FDA's Division of Pharmaceutical Analysis analyzed the ingredients in a small sample of cartridges from two leading brands of e-cigarettes. In releasing its information, the FDA did not identify the two companies, but said in one sample, diethylene glycol -- a chemical used in antifreeze that is toxic to humans -- was detected. Other samples detected carcinogens that are dangerous to those who smoke them, the FDA said. The FDA has been examining and seizing shipments of non-U.S.-made e-cigarettes at the U.S. border since summer 2008. To date, 50 shipments have been stopped. The products examined thus far meet the definition of a combination drug-device product under the Federal Food, Drug, and Cosmetic Act. "We know very little about these devices, said Dr. Jonathan Samet, director of the Institute for Global Health at the University of Southern California, "but to say they are healthy -- that's highly doubtful."

QUES: While Nashiri was in Afghanistan, Nibras and Khamri saw their chance. They piloted the explosives-laden boat alongside the USS Cole, made friendly gestures to crew members, and detonated the bomb. Quso did not arrive at the apartment in time to film the attack. Back in Afghanistan, Bin Laden anticipated U.S. military retaliation. He ordered the evacuation of al Qaeda's Kandahar airport compound and fled- first to the desert area near Kabul, then to Khowst and Jalalabad, and eventually back to Kandahar. In Kandahar, he rotated between five to six residences, spending one night at each residence. In addition, he sent his senior advisor, Mohammed Atef, to a different part of Kandahar and his deputy, Ayman al Zawahiri, to Kabul so that all three could not be killed in one attack. There was no American strike. In February 2001, a source reported that an individual whom he identified as the big instructor (probably a reference to Bin Laden) complained frequently that the United States had not yet attacked. According to the source, Bin Laden wanted the United States to attack, and if it did not he would launch something bigger. The attack on the USS Cole galvanized al Qaeda's recruitment efforts. Following the attack, Bin Laden instructed the media committee, then headed by Khalid Sheikh Mohammed, to produce a propaganda video that included a reenactment of the attack along with images of the al Qaeda training camps and training methods; it also highlighted Muslim suffering in Palestine, Kashmir, Indonesia, and Chechnya. Al Qaeda's image was very important to Bin Laden, and the video was widely disseminated. Portions were aired on Al Jazeera, CNN, and other television outlets. It was also disseminated among many young men in Saudi Arabia and Yemen, and caused many extremists to travel to Afghanistan for training and jihad. Al Qaeda members considered the video an effective tool in their struggle for preeminence among other Islamist and jihadist movements.
