On the morning of Tuesday, May 28, 2013, thousands of workers, who are paid their wages for their work on a day to day basis, started a major protest  [ar] in Zouérat , the capital of Tiris Zemmour state in north of Mauritania, demanding proper contracts and rights as well as ending the monopoly of businessmen over the Arab Mining Company (ARMICO). The workers headed to the administrative headquarters of the state before anti-riot units suppressed the protest. The workers retaliated by occupying the state building, the premises of one of the contractor companies, as well as the state radio buildings. The army  [ar] intervened to control the situation and stop the workers protests.
Activist Magdy Ahmed tweeted about the escape of the governor of Tiris Zemmour after the workers protests [ar]:
@mejdmr  :والي ولاية زويرات الجنرال ول باهية و الوالي المساعد وشرطة المدينة يفرون أمام غضب عمال الجرنالية الذين اقتحمو مبني الولاية والإذاعة الجهوية
@mejdmr : The governor, Ould Bahia, the deputy governor and the police ran away after witnessing the one-day workers anger when they occupied that governorate and state radio headquarters.
