More than 12,800 Yemenis, including women and children, have been killed in the course of the Saudi military aggression against neighboring Yemen since March 2015.
This is while international right groups have repeatedly condemned Riyadh over its onslaught against Yemen. They have also warned of a humanitarian crisis in the impoverished country.
The Saudi campaign was launched with the aim of reinstating Yemen’s former president Abd Rabbuh Mansur Hadi.
Hadi, a loyal Riyadh ally, resigned last year and fled to the Saudi capital. He later returned to the country’s port city of Aden.
Hadi has rejected a United Nations peace roadmap, saying the initiative favors Ansarullah movement, while the movement is the main popular base which has been defending the country against the Saudi invasion.
