A Tunisian politician was assassinated on Wednesday sparking protests across the country.

Tunisian President Moncef Marzouki, who was on a visit to the European Parliament, condemned the killing:
“This is a heinous murder of a political leader who I know well,” he said. “Who has been my friend for a long time, Chokri Belaid.
“This is a political assassination, knowing today, at this time, they knew I would be speaking to you. It is a threat, it is a letter, but it won’t be received, we refuse, we reject this letter, we reject the message and we will continue to expose the enemies of the revolution.”
The President has cut short his visit to France and cancelled a scheduled appearance at a summit in Egypt to return home.
Belaid was a leading member of the opposition Popular Front Party and a constant critic of the government accusing it of being a puppet of Qatar.
