The farming town of Siliana has been a hotbed of political opposition since long before the revolution.
Last week's murder of secular opposition figure Chokri Belaid in Tunis, ignited angry protests.
In elections that followed the revolution, the Ennadha party, which is now in power, was embraced.
But now many blame the party for failing to prevent Belaid's death.
