In Tunisia, thousands of people are gathering in the capital to pay their respects to opposition leader Chokri Belaid, who was assassinated on Wednesday.
Mr Belaid was an outspoken critic of the Islamist-led government that came to power following the uprising two years ago, and his death has sparked country-wide protests.
BBC Arabic's Reda El Mawy says there are fears in Tunisia and the wider region of further unrest following the death of Chokri Belaid.
