Tunis: Six people belonging to Tunisia’s hardline Salafist movement have each been handed five year jail sentences for torching an important Sufi shrine, the country’s Sufi union said on Tuesday.

“It’s the first time such a sentence has been pronounced. It shows that the law can be applied in Tunisia when the political will exists,” Mohammad Al Heni, one of the union’s leaders, said.

Four of those convicted were already in custody while the remaining two are on the run, he added.

They were sentenced on Monday over an arson attack last October on the tomb of Saida Manoubia in the capital, one of the country’s main Sufi shrines, which was completely gutted.

The attack came amid a spate of similar violence by Tunisia’s increasingly assertive Salafists who consider that venerating saints and their shrines is blasphemous and contrary to Islam.

According to the Sufi union, some 50 holy sites were targeted between last summer and early 2013, but Heni said “no arrests have taken place except in the case of the Manoubia shrine”.

He said one reason for this was the fact that the attacks took place at night in remote areas, but also because of “laxity by the public authorities” towards the Muslim extremists.

Heni mentioned in particular that no one had yet been arrested over the fire in January that destroyed the famed mausoleum of Sidi Bou Said, a prime tourist destination also in a suburb of Tunis.

The ruling Islamist party Al Nahda “has not entirely cut the cord with the Salafists,” he said.

Since the revolution that overthrew Zine Al Abdine Bin Ali in January 2011, radical Islamists suppressed under the former dictator have been implicated in a wave of attacks, often targeting Sufi shrines and cultural festivals, and culminating last September in an assault on the US embassy.
