Protesters throw stones amidst smoke during clashes with riot police near the Interior Ministry in Tunis
Thousands of Islamists marched in Tunis on Saturday in a show of strength, a day after the funeral of an assassinated secular politician drew the biggest crowds seen on the streets since Tunisia's uprising two years ago.
About 6,000 supporters of the ruling Ennahda movement rallied to back their leader Rachid al-Ghannouchi, who was the target of angry slogans raised by mourners at Friday's mass funeral of Chokri Belaid, a rights lawyer and opposition leader.
"The people want Ennahda again," the Islamists chanted, waving Tunisian and party flags as they marched towards the Interior Ministry on Habib Bourguiba Avenue in the city centre.
According to Reuters, the demonstration was dwarfed by the tens of thousands who had turned out in Tunis and other cities to honour Belaid and to protest against the Islamist-led government the day before, shouting slogans that included "We want a new revolution".
Belaid's killing by an unidentified gunman on Wednesday, Tunisia's first such political assassination in decades, has shaken a nation still seeking stability after the overthrow of veteran strongman Zine al-Abidine Ben Ali in January 2011.
The family of the slain politician has accused Ennahda of responsibility for his killing. The party denies any hand in it.
"We are here to support legitimacy, but if you prefer the power of the street, look at the streets today, we have this power," Lotfi Zitoun, an Ennahda leader, said in a speech to the Islamist demonstrators in Tunis.
Tunisia's political transition has been more peaceful than those in other Arab nations such as Egypt, Libya and Syria, but tensions are running high between Islamists elected to power and liberals who fear the loss of hard-won liberties.
