The World Health Organization had earlier said initial tests of four products found unacceptable levels of potentially toxic chemicals.

The children died from acute kidney failure after taking the medicines produced by Maidan pharma and exported to The Gambia.

Maiden Pharmaceuticals says it adheres to internationally recognised quality-control standards.

But some of its products have failed to meet national or state-level quality-control standards in India.

India produces a third of the world's medicines, mostly in the form of generic drugs.
