Ostracism was an Athenian democratic procedure in which citizens voted each year on whether to expel someone from the city for ten years. Each voter scratched the name of the person he wanted removed onto a piece of broken pottery, called an ostrakon, and the man with the most votes, provided enough people had voted, was sent away. It was often used preemptively, to neutralise someone seen as a potential tyrant, rather than as punishment for a crime. The exile kept his property and could return after ten years.

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.
