A condominium in international law is a territory jointly governed or owned by two or more sovereign states, and the arrangement has existed in many forms. Sudan was a condominium of Britain and Egypt from 1899 to 1956, and Bosnia was jointly ruled by Austria and Hungary from 1908 to 1918. Border areas and water bodies are common sites for these arrangements: the Gulf of Fonseca has been shared by Nicaragua, El Salvador and Honduras since 1980, and Norway and Russia shared a border district from 1684 to 1826. The smallest example is Pheasant Island in the Bidasoa River, which France and Spain share and rule in alternating six-month periods. Maps often show these territories poorly, because cartographers have to choose how to depict shared sovereignty.

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.
