As you can see, there was no shortage of al-Qaeda flags.

(Reuters) – Tens of thousands of supporters of Tunisia’s Islamist-led government marched in the capital on Saturday, one of the biggest in a series of pro-government and opposition rallies sparked by the assassination of a secular politician.

The February 6 killing of Chokri Belaid, a human rights lawyer and opposition leader, has thrown Tunisia into political turmoil two years after it staged the first of the “Arab Spring” revolts.

Violent protests, in which one policeman was killed, swept Tunisia after the assassination, with crowds attacking Ennahda offices in Tunis and elsewhere. Protesters shouted slogans against the Islamist party elected to power in 2011, including “We want a new revolution”.

Islamists have launched counter rallies, up to now much smaller.

After Belaid’s death, Prime Minister Hamadi Jebali promised to form a non-partisan, technocratic cabinet to run the country until an election could take place, despite complaints from within his own Ennahda party and a junior non-Islamist coalition partner that he had failed to consult them.
