Yemenis on Friday have held a demonstration in the city of sa'dah to commemorate the martyrdom anniversary of the founder of the Ansarallah movement.
Hussein Badreddin al-Houthi was martyred in 2004 while leading a revolt against the then-Saudi-backed regime.
Saudi Arabia and its regional allies attacked Yemen in March 2015 to bring back to power the deposed president of the country, Abdrabbuh Mansour Hadi.
The Saudi aggressors have committed horrible war crimes against Yemeni civilians during the past three years.
The United Nations says 10,000 people have died in the three-year-old war, and three out of four Yemenis — 22 million civilians — need relief aid.
