Houthi masses have headed to the capital Sana'a after the Saada-based group agreed with the former president Ali Abdullah Saleh to coordinate their work, local sources said on Wednesday.
Residents of the northern governorate of Saada complain that the Houthi group has increased its repression, crackdown and violations against those people who do not embrace its ideologies.
They spelt out that the group took capture on some mosques, arrest their imams and replace them with others affiliated to the group, pointing out that the literatures of other Sunni groups were confiscated and burnt by the group from mosques.
The sources said the group carries out an arrest campaign against of local residents of Saada governorate for unknown reasons, indicating that residents of Saada were arrested as they were affiliated to sanctions.
They emphasized that Houthi gunmen threatened locals after media outlets released news stories about violations practiced by the Houthi group.
Meanwhile, UN Envoy to Yemen Jamal Benomar called the group on Wednesday to turn to a political party, take part in the political process and renounce violence.
An officer of Human Rights Watch in Yemen Abdul-Rashid Al-Faqih has called to investigate crimes committed by the Houthi group in Saada after he visited four persons who were brutally tortured by the group, according to Al-Faqih.
He said that the three persons were captured from their homes in Saada last Thursday, held in solitary confinements and they were only released after they pledged to not participate in any political, cultural or social activities.
"We receive many calls from Saada governorate in which residents complaints of violations and repressions carried out by the Houthi group" he added.
A Yemeni rights group, Hood, that visited the persons said that their conditions are very deteriorated and that they were transferred to Sana'a hospitals.
