The former military ruler of Argentina, who is accused of human rights abuses, has been transferred to prison after being under house arrest. Jorge Videla, 83, was convicted in 1985 of the murder of 66 people, the torture of 93 others, and the illegal detention of over 300. Videla, who ruled from 1976 to 1983, was jailed for life, but was pardoned by President Carlos Menem in 1990.
