Saleh's General People's Congress (GPC) party issued a statement announcing that members of Guard Brigade Tareq Mohamed Abdullah Saleh were killed during clashes against Houthis on Thursday.

Houthis launched an armed attack, and clashes sparked due to targeting houses of the party leaders and relatives of Saleh, according to the statement that clarified that Saleh forces were shocked with the offensive.

The statement also hinted on Houthis not wanting to abide by the truce.

Yemen insurgents' clashes disclosed confessions of a Houthi figure that there are arms in a mosque in Sana’a. Meanwhile, internal clashes continued in Sana’a for the second day in a row.

Sources to Asharq Al-Awsat said that tribal mediation and other by Saleh Al-Samad, head of the Supreme Political Council, endeavored to alleviate the tension yet it continued to rise.

Disputes aggravated between Houthis and Saleh. Al Arabiya reported from sources in Sana’a that Houthi militias besieged the house of foreign minister in Hisham Sharaf government. Also blasts were heard near to houses of Saleh relatives.

The fake version of Saba News Agency accused Saleh forces of hiding arms including RBG.

Houthis justified their offensive on Saleh forces, saying that the security bodies found inside Saleh Mosque a number of repeaters for wireless telecommunication, which are only used by the state and its security and military bodies.

On the other hand, three fighters from forces loyal to the former Yemeni president Ali Abdullah Saleh were killed in a second day of clashes with their own allies from the Houthi movement in the capital Sanaa, Saleh’s party said on Thursday.

The two groups are fighting a Saudi-led coalition that has intervened in a 2-1/2 year Yemeni civil war with a view to restoring the internationally recognized government of President Abd-Rabbu Mansour Hadi.

A statement from Saleh’s General People’s Congress Party said three guards were killed when Houthi forces attacked the house of Tarek Saleh, Ali Abdullah Saleh’s nephew, adding that they also besieged the residence of Ibrahim Sharaf, a party member and foreign minister of the Sanaa-based government.

“The Houthis violated the truce agreement and attacked the residence of colonel Tarek and killed three guards and wounded three others,” the statement said.

The clashes underscore the complex situation in Yemen, as Hadi’s alliance has also seen similar internal fighting between his contingents and pro-independence southern forces backed by the United Arab Emirates, a key member of the Saudi-led coalition

Local sources told Reuters some residents fled areas where the fighting, which involved heavy artillery and rocket launchers, raged for several hours for a second day.

Four supporters of Ali Abdullah Saleh were killed when a gunfight erupted on Wednesday in the center of Sanaa, after the Houthis broke into the city’s main mosque complex and fired RPGs and grenades.

Houthi fighters and battalions loyal to Saleh made common cause to fan out through Yemen in 2015 and have weathered thousands of air strikes launched by neighboring Saudi Arabia and its allies. Hadi’s government is nominally based in the port city of Aden.
