April 1, Tunisian President al-Moncef Marzouki extended by one month state of emergency in force due to instability in the country.
The state of emergency was declared in Tunisia January 14, 2011, after the fall of the regime of Zine el-Abidine Ben Ali. Since then, the Tunisian authorities have extended three times: February 14, July 26 and November 29. This repressive measure allows police and the army to shoot the suspects who refuse to comply.
