Ethiopia: presser of former political prisoner disrupted Ethiopian journalist and former political prisoner Eskinder Nega's press conference is disrupted by half a dozen young men brandishing Ethiopian flags, calling him a liar and accusing him of stoking tensions among ethnic groups. Nega says the government is using last month's assassination of high-ranking officials as a pretext to arrest critics, in a return to repressive tactics used by past governments.
