An Egyptian court sentenced an activist to six months in prison on Monday on charges that he insulted President Mohamed Morsi and circulated false news on television. The prison sentence is the first for insulting the president since Mr. Morsi came to power last year. The activist, Ahmed Douma, was expected to post bail and be released on Monday pending the appeal of his case. He was arrested in April after calling Mr. Morsi a killer and criminal, which the court ruled could undermine state security. Egypt has seen a sharp rise in court cases for libel and blasphemy since the revolution in 2011.
