The UN expert also slammed a Saudi-led airstrike, which hit a refugee camp in northern Yemen on March 30, describing it as a grave violation against some of the most vulnerable of the vulnerable civilians.
Saudi Arabias military aggression against Yemen started on March 26, without a UN mandate, in a bid to restore power to the former president, Abd Rabbuh Mansur Hadi.
Several hundred people have so far been killed and many more injured in the Saudi attacks on Yemen.
The UN says at least 74 children have been killed since the beginning of the Saudi-led strikes. The real figure is thought to be much higher. The turmoil has forced over 100,000 people from their homes.
Reporting from the site of a Saudi air raid in Sanaa, Press TV correspondent Yousef Mawry said a ten-story building had been targeted, two stories of which have been wiped out.
