Hundreds of demonstrators took to the streets in the northern Moroccan city of Tangier on Saturday to protest over high prices for water and electricity, despite government assurances and calls to end the rallies. Saturday night's protest was the latest in a series of rallies that started three weeks ago. It took place days after authorities said the government was working with the French-owned company running the services to review the bills and called the city's population to stop protesting. Still, the rally was smaller than last week in Tangier when thousands protested in Morocco's largest street demonstration since the 2011 pro-democracy protests. A statement from the government earlier this week warned "citizens to not follow those who want to make mischief." It also said the interior minister has given strict orders to the company to execute the bill review measures as soon as possible. Water, wastewater and electricity businesses in the cities of Tangier and neighboring Tetouan have been operated since 2002 by Amendis, an affiliate of France's Veolia Environnement. Redal, another Veolia subsidiary, is operating in the capital Rabat, Sale and the municipalities of Temara and Bouznika. After the 2001 Arab Spring, an Islamist-led government took power for the first time in Morocco and made structural reforms, in particular in public finance, its top priority. It started with reducing the cumbersome subsidies which led to rising prices of water and electricity. Last year, Moroccan local authorities blocked a deal by Veolia Environnement to sell its businesses in Morocco to investment fund Actis for about 370 million euros ($504 million) due to a dispute over investments. Sources from the company and from the government said Veolia dropped the sale plan and convinced authorities to review the concession contracts. The review is yet to be approved by the local councils in cities where the company has been involved.
