>> Another night of violent protests has hit Tunisia as these demonstrators defy to government's threat of a wider crackdown. This graffiti says you're suffocating us, and it cuts to the heart of the crisis. It's hard times for many in Tunisia. Government's recent decision to increase prices on staple items and gasoline and impose new taxes was just too much for some.
Reuters Aiden Lewis is in capital Tunis, one of the cities hit.>> On the streets in Tunis this morning the situation looks calm. Shops are opened. People are going to work as usual and the reason for that is these protests have been following a familiar path with calm in the morning and then protests in the afternoon.
And then an escalation often after dark. And that's what's happened in previous years as well.>> At least 20 locations, including Tunis, have been hit by the protests since they started on Sunday. Around 600 arrested. This is the ninth government to take power since 2011's Arab Spring. When protesters overthrew their authoritarian leader, none of them have been able to deal with country's growing economic problems.
Those price hikes were aimed at tackling their deficit and foreign debts. Now Prime Minister Youssef Chahad said enough is enough. The state won't bow to violence.>> The relationship between the protestors and the police is particularly difficult. The army has now been sent to several towns. Partly because the army has a better reputation in Tunisia than the police, who are often mistrusted for their role under the previous regime.
>> Some law makers have called for an increase to the minimum wage but its likelihood is unclear. There is also concern that small numbers of radical Islamist may be trying to take advantage of the crisis. The interior ministry said at least two has been found among those detained.
