New clashes between Houthis an Salafists in the north of Yemen

The Yemen Post reported on Friday  that clashes between Salafists and Houthis escalated in the north of Yemen and that 14 fighters from both sides were killed in the fighting in two days.
More than 85 people have been killed over the last month in this kind of sectarian violence in the northern governorate of Sa’ada. The Houthi movement now controls Sa’ada after six long wars with the government since 2004. Houthis rejected the latest GCC power transfer proposal and called it a catastrophe that will never be forgiven by the Yemeni people.
Eyewitnesses on the ground said that although the Houthis were having the upper hand in the fighting  of the last days, Salafi militants succeeded in taking over checkpoints and military positions previously under the control of the Houthis. Mediation committees were formed between both sides to help end the conflict and hundreds of tribal and political leaders tried to help end the crisis, but to no avail.
The Houthis are Zaidis, which is a branch of Shi'ite Islam, the Salafists are Sunni fundamentalists.
