Asked if independent international bodies have confirmed the test results, the renowned specialist lamented that the World Health Organization [WHO] has also confirmed the drugs were infected with AIDS virus.
Dr. Karim said that he and Yemeni physicians have found out all the drugs had come from Saudi Arabia.
A US-led Saudi aggression has been attacking Yemen since March 26 - without a UN mandate.
The aggression has killed more than 2,000 civilians, displaced more than a million and led to severe shortages of food, water, fuel and electricity.
More than 21 million people -- 80 per cent of Yemen’s population -- need humanitarian aid and one million have been displaced in the fighting.
More than 20 million people lack access to water while the collapsing health care system is facing an outbreak of dengue fever and malaria in the south and in areas bordering Saudi Arabia.
A near-blockade of Yemen’s ports has made it very difficult to deliver humanitarian aid as well.
