Tunisia, widely seen in the West as the only democratic success among nations where “Arab Spring” revolts took place in 2011, is suffering increasing economic hardship.
Anger has been building up since the government said that, from Jan. 1, it would increase the price of gasoil, some goods, and taxes on cars, phone calls, the internet, hotel accommodation and other items, part of austerity measures agreed with foreign lenders.
The 2018 budget also raises customs taxes on some products imported from abroad, such as cosmetics, and some agricultural products.
