The accordion's basic form is believed to have been invented in Berlin in 1822 by Christian Friedrich Ludwig Buschmann. An instrument called accordion was patented in Vienna in 1829 by Cyrill Demian, whose early design was a bellows-driven instrument with a left-hand keyboard that sounded whole chords with one key. The instrument spread to Britain around 1828 and to Russia by about 1830, where Tula makers mass-produced it. Charles Wheatstone joined chords and melody keys in one squeezebox in 1844. Later innovations added switchable voices, electronics and MIDI.

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.
