Sa'ada security apparatuses are conducting investigations into the killing incident of Parliament Member Saleh Saleh Daghsan who was trapped along with his bodyguards and companions last week in Al-Safara district's Al-Khiam area.

Daghsan's son and Sheikh Mohammed bin Mohammed Da'kem were also killed in the incident while four other companions were injured, most of them critically.

Though local sources blame early revenge killings for the incident, Houthi followers and Sa'ada officials exchange accusations over who is to blame for the incident.

Daghsan and his son were buried early this week in their homeland, Al-Qaflah village, part of Al-Safara district's, Al Ammar area. The area was a position for Houthis during the different wars between Houthis and the army.

Yemeni parliament demanded security authorities to make a quick arrest of perpetrators in order to refer them to judiciary to meet just punishment.

Joint Meeting Parties denounced the incident and demanded authorities to penalize those involved, and to work for avoiding any new tension that could affect the social situation there.

In a letter sent to Daghsan's brother, Houthi lamented his death and described him as one of their leaders, while he was considered by most to be among the people who reacted against Houthi rebels and backed government authorities.

In revenge killing, Sa'ada witnessed a tribal and civil war on April 5 in Kitaf district. The war involved tribesmen from Al Bakhtan and Houthi rebels and resulted in killing 15 people of both sides.

The war was fought by Al Bakhtan in retaliation for killing Sheikh Sha'ie Bakhtan and three of his bodyguards on February 12.

In a program aired by Al-Jazeera Channel, Sa'ada governor Brig. Mutahar Rashad Al-Masri blamed Houthi loyalists for assassinating Daghsan, while Houthi field leader Abdul Malik Al-Houthi hinted the operation was launched by authorities.

Local sources told the Yemen Post that Daghsan's death could have gross consequences on the situation in Sa'ada, especially when the province faces exceptional circumstances while authorities are seeking to restore peace and security once again.

They also expressed fear over the eruption of national wars and revenge killings particularly when such acts targets leaders and social dignitaries of the province and thus fueling the would-be war.

The operation came after the presidential committee responsible for implementing Sa'ada ceasefire agreement announced it will not return to Sa'ada until Houthis show seriousness to implement the agreement articles.

Sources close to the presidential committee stated to the Yemen Post that Daghsan's death will affect the agreement because he was not involved in its work. They also revealed that the Qatari members returned on Sunday to Sana'a, hinting this is because of the tense situation in the province.
