Area 51 is a highly classified United States Air Force facility inside the Nevada Test and Training Range, about 83 miles north-northwest of Las Vegas. Its official name is Groom Lake, after a nearby salt flat, and the Air Force and the CIA acquired the site in 1955, mainly to test the Lockheed U-2 spy plane. The government did not confirm the base's existence until 2013, when the CIA released declassified documents. Its secrecy has made it a central part of UFO folklore, though the disputed claims about alien evidence have no credible support. Today the surrounding area draws tourists to towns such as Rachel, along the Extraterrestrial Highway.

Israeli reports also say the cabinet directed the military to prepare for a possible new attack on Iran.

Angkor, near Siem Reap in northern Cambodia, was the capital of the Khmer Empire, which ruled much of mainland Southeast Asia between roughly the 9th and 15th centuries. At its height the city spread across about 3,000 square kilometres, making it the largest pre-industrial city on Earth by area. Its growth depended on water: huge reservoirs called barays, along with canals and embankments, stored monsoon rain and carried it to rice fields. That system let farmers harvest more than once a year and fed a very large population through the dry season. The temple complex of Angkor Wat, built in the early 12th century, is the best-known monument and still stands at the heart of the park.
