Surfing means riding a wave on a board, or sometimes on the body alone. Ancient cultures rode waves on their bellies and knees, the Moche of Peru used reed craft, and Pacific peoples used boards such as the alaia. Modern surfing is mostly stand-up, with several styles including longboarding, shortboarding and stand-up paddling. Big-wave surfers are often towed into waves by jet skis to match their speed. The largest wave ever surfed was 26.2 metres high, ridden by Sebastian Steudtner at Nazare in Portugal, as recognised by Guinness World Records. Surfing became an Olympic sport at the Tokyo 2020 Games.

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.
