The death of Mr Belaid, a leading critic of the governing party has proved to Tunisians what they already feared, says our correspondent, and Friday's funeral is certain to be an emotional and highly charged event. Government critics say that in recent months, Ennahda has allowed ultra-conservative Muslim groups to impose their will and opinions on what was always regarded as a bastion of Arab secularism.

(Reuters) - Tunisia's ruling Islamists dissolved the government and promised rapid elections in a bid to restore calm after the killing of an opposition leader sparked the biggest street protests since the revolution two years ago. The prime minister's announcement late on Wednesday that an interim cabinet of technocrats would replace his Islamist-led coalition came at the end of a day which had begun with the gunning down of Chokri Belaid, a left-wing lawyer with a modest political following but who spoke for many who fear religious radicals are stifling freedoms won in the first of the Arab Spring uprisings.

In Tunis, the crowd set fire to the headquarters of Ennahda, the moderate Islamist party which won the most seats in an legislative election 16 months ago.

Prime Minister Hamdi Jebali of Ennahda spoke on television on Wednesday evening to declare that weeks of talks among the various political parties on reshaping the government had failed and that he would replace his entire cabinet with non-partisan technocrats until elections could be held as soon as possible.

The government of Prime Minister Hisham Qandil is currently in the process of drafting two new laws aimed at regulating the right of street protest and combating the proliferation of thuggery

the Committee on National Defence launched scathing attack against private TV satellite television channels, taking them to task for alledgely inciting protesters to launch violent attacks on several state buildings in recent days, notably Al-Ittihadiya presidential palace in Cairo's district of Heliopolis on 1 February

The 26-article law also makes it obligatory that the interior ministry be notified of any given protest or demonstration's date, objective and site. The notification request must be submitted to the ministry five days in advance of the date of the demonstration. The interior ministry reserves the right to forbid "demonstrations" or "public gatherings and meetings" if they risk "disrupting public peace and security."

Social media narratives are appealing because they allow us to create our own feel-good stories about revolution

This social media ‘revolution’ was really about how the west experienced events in Egypt

Traditional media works differently: commenters tell you what to think by repeating their droning analyses hourly on 24-hour news channels. Their well-staged shots provide an overview of the scene and their description of events pretends to be ‘objective’ and comprehensive. In short, there is little room for engagement with information which is dictated to you and which is placed firmly within a specific context.

Egypt's feuding politicians renounced violence on Thursday after being summoned by the country's most influential Muslim scholar to talks to end the deadliest unrest since President Mohamed Mursi took power. It remains to be seen whether the pledge to end confrontation will halt a week of bloodshed on the streets that killed nearly 60 people. Opposition groups did not cancel new demonstrations scheduled for Friday. But participants at the meeting, including leaders of Mursi's Muslim Brotherhood and its secular rivals, described their joint statement as a major step towards ending a conflict that has made the most populous Arab state seem all but ungovernable two years after an uprising toppled autocrat Hosni Mubarak.

Al-Azhar, one of the main seats of learning in Sunni Islam worldwide, has tended to keep itself above Egypt's political fray. Its extraordinary intervention follows a warning by the army chief on Tuesday that street battles - which erupted last week to mark the second anniversary of the uprising that toppled Mubarak - could bring about the collapse of the state.

The secularists are nonetheless likely to continue to press for inclusion in a national unity government, a call also backed by the hardline Islamist Nour party in an unlikely alliance of Mursi's critics from opposite ends of the political spectrum. The Brotherhood rejects a unity government as an attempt by Mursi's foes to take power they could not win at the ballot box.
