Hundreds of thousands of pro-Houthi protestors on Sunday held a massive rally in Sanaa, commemorating the second anniversary of what they have called the Saudi aggression against the Yemeni people.

Protestors flocked to the square after former president Ali Saleh and the Houthis' leader urged their supporters to gather in Al-Sabeen Square of Sana'a.

Riyadh intervened in support of the government of President Abedrabbo Mansour Hadi, who had been ousted from Yemen's capital by Houthis.

The war in Yemen has cost more than 10,000 lives since March 2015 and brought the country to the brink of famine.
