Iguazú Falls is a system of waterfalls on the Iguazu River along the border of Argentina's Misiones province and Brazil's Paraná state, and together they form the largest waterfall system in the world. The river splits them into an upper and a lower section, and most of the falls lie on the Argentine side even though most of the river flows through Brazil. According to a Guarani and Tupi legend, a deity sliced the river to punish a mortal couple who eloped, creating the falls and condemning the lovers to fall forever. The first European known to record the falls was the Spanish conquistador Álvar Núñez Cabeza de Vaca in 1541.

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.
