Tunis - Tunisian police fired tear gas and clashed with protesters on Friday as tens of thousands joined the funeral of opposition leader Chokri Belaid whose murder plunged the country into new post-revolt turmoil.
Skirmishes erupted on the margins of the funeral procession which turned into a demonstration in Tunis, a city paralysed by a general strike called in protest at Wednesday's assassination of the leftist leader.
The interior ministry said 132 people were arrested and estimated the size of the funeral crowd at 40,000.
“With our blood and our souls we will sacrifice ourselves for the martyr,” shouted mourners, who also chanted slogans denouncing the ruling Ennahda party as “assassins”.
Belaid's widow Besma held two fingers in the air in a victory sign as a chant of “The people want a new revolution” rang out.
The murdered politician's eight-year-old daughter fainted amid the chaotic and emotional scenes as the procession set off on its three-and-a-half kilometre (two-mile) journey to the cemetery.
“My son is a man who lived with courage and dignity. He was never afraid, he left as a martyr for our country,” said Salah Belaid, his father.
“We lost a great hero,” Beji Caid Essebsi, a former prime minister who is now a centre-right opposition leader, told AFP.
The opposition has accused Ennahda, the Islamist party that dominates the ruling coalition, of eliminating the outspoken government critic after months of simmering tensions between liberals and Islamists over the future direction of the once proudly secular Muslim nation.
Police fired tear gas to disperse groups of rioters who tried to set fire to a dozen cars opposite the cemetery in southern Tunis, sending up thick plumes of smoke and causing some panic.
Mourners jostled for space with news photographers before the burial.
Hamma Hammami, a leader of the Popular Front, the alliance of leftist parties to which Belaid belonged, gave a graveside oration, followed by a minute's silence.
“Rest in peace, Chokri, we will continue on your path,” Hammami told the huge crowd of mourners thronging El-Jellaz cemetery.
In the city centre, police wielding batons and firing tear gas clashed with youths who chanted anti-government slogans on Habib Bourguiba Avenue.
Armoured vehicles and troops deployed along the landmark boulevard, epicentre of the 2011 revolution that toppled autocratic president Zine El Abidine Ben Ali and sparked a wave of Arab world uprisings.
Belaid, 48, was shot dead at close range by a lone, hooded gunman as he left home for work on Wednesday.
As a general strike called by the powerful General Union of Tunisian Workers (UGTT) took hold, troops were deployed in the towns of Zarzis, another flashpoint in the south and Sidi Bouzid, birthplace of the 2011 uprising.
Police fired tear gas to disperse a demonstration in the central mining town of Gafsa, the scene of sporadic rioting in the aftermath of Belaid's killing.
The general strike is believed to be the biggest since January 14, 2011 - the day Ben Ali fled to Saudi Arabia, where he remains in exile.
“For us it is a landmark event because it is a real turning in the history of Tunisia,” said Habib Kazdaghli, the dean of Manouba University, explaining why academics had joined the strike.
The United States joined both the 500,000-strong UGTT and the Tunisian government in appealing for calm after two days of violence left one police officer dead, another in a coma and scores of people injured.
Prime Minister Hamadi Jebali responded to the outrage by saying he would form a government of technocrats.
But a faction of his Ennahda party rejected the move, fuelling uncertainty as political infighting delays a deal on a new constitution.
Any reshuffle would also have to be confirmed by the national assembly.
Four opposition groups including the Popular Front said they were pulling out of the National Constituent Assembly, elected in October 2011 but which has failed to draft a new constitution.
The Tunisian League for Defence of Human Rights said threats and intimidation were continuing under the Ennahda-dominated government, and called for politicians to be protected.
Pro-Ennahda militias have been accused of organising attacks on secular opposition groups already at loggerheads with the party over the constitution.
