“Nobody likes the situation and this government has to change,” said Rabbeh Souly, 28, who sped up her steps on the pavement in central Tunis after witnessing a mugging. “They need to fix the things that concern people like unemployment and poverty. Before, at least things were calm and safe. I regret Ben Ali is gone.”
She was speaking of the longtime dictator Zine el-Abidine Ben Ali, who was ousted two years ago. His departure ushered in a transition coalition government led by the Islamists.
Now Tunisia is at a crossroads. Violence has been escalating for months and the general political atmosphere has been deteriorating. This was underscored by the murder of leftist opposition leader Chokri Belaid, who was shot in front of his house by unidentified assailants last week. The killing came as a shock to both ordinary people and to the political establishment.
Thousands of Tunisians took to the streets after Mr. Belaid’s death, vowing revenge in scenes reminiscent of the protests in 2011.
“With our souls, with our blood, we will avenge you Belaid,” they chanted in the rain on a march to the cemetery.
In the halls of government buildings, another drama played out. The prime minister, Hamadi Jebali, called for the government to resign in favor of a technocratic leadership. But his own Ennahda party disavowed his call.
Ennahda, a moderate Islamist party, has been the strongest political group following the departure of Mr. Ben Ali, winning elections in October 2011 handily because it was viewed as very different from the strongman and his cronies.
But after the assassination of Mr. Belaid, the party has been forced into retreat, while the secular leftist opposition has been given new momentum and unity.
“The country entered a new political cycle: It was in a difficult political transition that was marked by phases of instability and now we are seeing a radicalization of political actors,” said Vincent Geisser, a researcher at the French Institute for the Near East who is based in Beirut, speaking of Islamists and secularists. “There is a serious need for dialogue before there is another assassination.”
The challenges are real: The country is dealing with a weak economy that contracted by 1.8 percent in 2011 and grew by an estimated 2.7 percent last year — not enough to reduce unemployment, which is running at about 17 percent, up from 13 percent at the end of the old regime.
Political instability is also frightening away tourists. Tourism was a key source of jobs and income in the past.
The turmoil is hurting just about everyone.
“Political parties are fighting and the Tunisian people are paying for it,” said Mohamed Ben Amor, sweeping in front of a bodega after a protest on Avenue Bourguiba. “The country is deeply affected by the problems that are happening, so business has been really bad.”
Tunisians lay the blame at Ennahda’s door for failing to address the roots of popular discontent and maintain order in the country, while creating an atmosphere in which religious radicals get away with making violent threats against the secular opposition.
Violence has been escalating in Tunisia over the past two years. Extremists have attacked tombs they consider sacrilegious and a TV station they believe has violated their conservative religious beliefs. In Sidi Bouzid, a city in central Tunisia, the extremist Salafis vandalized a bar in September.
Rachid Ghannouchi, a founder and leader of the Islamist party, who was recently called an “assassin” by demonstrators, strongly denies that the party has promoted violence.
“Ennahda never resorted to violence, it’s not part of our ideology,” he said during an interview in one of the party’s offices in Tunis.
“We are in power, but we feel like we are in the opposition. We don’t have any political party that stands by our party,” he added.
Even so, many blame Ennahda for the political turmoil and worry about a takeover by the military.
“Most Tunisians are held hostage by this kind of radicalization of the political spectrum,” Mr. Geisser said. “This stubbornness to not listen to each other could lead to a takeover by the security apparatus.”
Fares Mabrouk, a co-founder of the Arabic Policy Institute, a research concern in Tunis, believes that the shorter the transition period, the more chances the country has to get back to a more stable political climate. The current government is only supposed to remain until a constitution is in place and new elections are held.
“There is today an opportunity to create a historical compromise that will be unique to Tunisia, and unique in the Arab world,” he said. “The murder of Chokri Belaid and the unification of the left will balance the forces.”
The constitution is not finished and there is no date set yet for elections. This fight over political legitimacy is hurting the country.
“We have two equal forces and it can lead to civil war,” Mr. Mabrouk said. “The first one has electoral legitimacy and the other has now a martyr that is giving them legitimacy. With the political future so unclear, no Tunisian or foreign businesses will invest.”
But for many Tunisians, the murder of Mr. Belaid was a call to even greater political activism.
“I am in a state of shock, but actually there are thousands of Chokri Belaids,” said Mounji Ayari, 43, who wept as he held a sign with a picture of Mr. Belaid that read “martyr” at the funeral. “He is someone who taught us rebellion. He may be dead but he will forever stay with us and we will make sure his ideals live on.”
