Tokyo, Safar 3, 1435, Dec 6, 2013, SPA -- Japan's Diet late Friday approved a contentious secrecy law amid massive protests around the parliament building. dpa cited the government as saying the bill was necessary to protect all sensitive security information provided by the United States and other allies amid growing tensions in East Asia. However, there will be no guideline on what constitutes a secret, which will be decided on a case-by-case basis by the relevant minister, the government said. -- SPA 18:15 LOCAL TIME 15:15 GMT www.spa.gov.sa/1175866
