The party of Yemen's former president and strongman Ali Abdullah Saleh on Monday confirmed that he has been killed.
"In addition, the fault lines of the conflict pre-date Saleh's involvement with the Houthis and numerous foreign powers involved in the Yemeni conflict are driven by their own strategic interests in the region", he added.
Saleh announced on Saturday he was ready to turn a "new page" in ties with the Saudi-led coalition fighting in Yemen if it stopped attacks on Yemeni citizens, in a move that could pave the way to end almost three years of war, Reuters reported.
Media outlets Al-Arabiya and Reuters cited unnamed sources from Saleh's political party, the General People's Congress, as confirming that he was killed on December 4.
The former president's gamble in quitting his alliance with the Huthis proved to be a fatal step.
A video circulating online on Monday purported to show Saleh's body, his eyes open but glassy, motionless with a gaping head wound, as he was being carried in a blanket by rebel fighters chanting "God is great" who then dump him into a pick-up truck.
The fighting in the capital of Sanaa caused residents to cower in their homes as explosions rocked the city overnight.
The Houthi rebels' partnership with the powerful ex-president appeared to have fallen apart after he reached out to a Saudi-led coalition fighting the insurgents.
Conflict in Yemen
The wider Yemen conflict pits the Houthi-Saleh alliance against the Saudi-backed government of Hadi.
The apparent shift in position came as Saleh's forces battled Houthi fighters in Hadda, a district in southern Sanaa where members of Saleh's family, including his nephew Tareq, live.
The ex-president also called for an end to the "militia's rule on Yemen's land", adding that the Houthis had continued their "provocative acts against Yemeni citizens".
Saleh ruled Yemen for more than three decades until he was forced to resign following an Arab Spring uprising in 2011.

"Ambulances and medical teams can't access injured, people can't buy food and other supplies", UNICEF's Rajat Madhok said on Twitter.
In 2014, his forces allied with the Houthis despite the fact that as president he had gone to war with them on more than one occasion.
