Between 29 October and 2 November 2015, activists Mahmoud Yassin and Mohamed Ali Aboud Al Maliki were released by the Houthi-Saleh Coalition, after being detained incommunicado for more than two weeks at the Political Security Prison. Mahmoud and Mohamed had been arrested with 27 other activists by the Houthi-Saleh Coalition in October for organising a peaceful march to provide drinking water to the population of the besieged city of Taiz.
