Tunisian police used pepper spray Saturday to disperse protesters against President Kais Saied and a planned July referendum, nearly a year after he seized wide-ranging powers in what opponents decry as a coup.
The police blocked the protesters, who numbered around 100, as they attempted to reach the headquarters of the electoral commission, whose chief Saied replaced last month in a further extension of his control of state institutions.
Some at the protest in Tunis, organized by five small political parties, held up placards reading "the president's commission = fraud commission".
"The police... sprayed gas in our faces and attacked us," said Hamma Hammami, head of the Tunisian Workers' Party.
Saied on July 25 sacked the government and suspended parliament, which he later dissolved in moves that sparked fears over gains made after the 2011 revolution.
He has laid out plans for a referendum next month on a replacement of the 2014 constitution that had enshrined a mixed parliamentary-presidential system often plagued by deadlock and nepotism.
But the draft of the new constitution, which is to be put to the public in a simple yes/no vote, has not yet been published.
One placard at Saturday's protest read: "I don't need your referendum and I don't care about your constitution."
On April 22, Saied gave himself powers to appoint three of the seven members of the electoral commission, including the president.
Then last month he replaced commission chief Nabil Baffoun, a critic of the president's July power grab, appointing former commission member Farouk Bouasker to the position.
Saturday also marked the start of a national dialogue organized by Saied but boycotted by opponents, including the powerful UGTT trade union, on the grounds that it excludes key civil society actors and political parties.
Saied's opponents accuse him of moving towards an autocracy.
Some Tunisians however support his moves against a system they say achieved little in the decade since a 2011 revolt.
