On Monday, the Protection Cluster Yemen, which is part of the Global Protection Cluster, led by the UN refugee agency UNHCR, reported that the monthly average of airstrikes on Yemeni provinces are about three times higher in 2017 than that of 2016, and also that the attacks held by Ansarullah movement have raised steeply. As a result, Yemen is becoming the largest humanitarian crisis in the world.

Since 2015, Saudi Arabia has tried to recharge power to fugitive president Mansour Hadi, one of the allies of Riyadh, by striking Yemen and caused the death of more than 14,300 Yemenis.

Although Riyadh claimed that it is bombing the position of Ansarullah fighters, Saudi bombers are flattening the inhabitant places.

Several sources reported that although the Riyadh regime could not reach its goals, the Saudi-led air campaign against Yemen has drove the poor country towards humanitarian disaster.

The Al-Saud aggression has caused lots of damages on the country's facilities and buildings such as schools, hospitals and factories. They have also killed nearly 3.3 million Yemeni people, which include 2.1 million children.

It is also reported that since late April, as Saudi Arabia's campaign did not allow the patients to travel abroad for treatment and also banded the entry of medicine, about 2,000 people have been killed because of a cholera outbreak in war-torn Yemen.
