Scientists and defence experts have paid homage to Dr Abdul Qadeer Khan and lauded his contribution to Pakistan's nuclear weapon programme. Retired General Amjad Shoaib has revealed that Pakistan's medium-range missile Ghauri was also the outcome of Dr Khan's hard work. Scientists Samar Mubarakmand and Atta-ur-Rahman and Gen Shoaib spoke to SAMAA TV on Sunday as Dr Khan was laid to rest in Islamabad's H-8 graveyard. Dr Khan, 85, passed away Sunday morning and was given a state funeral. Nuclear physicist Samar Mubarakmand, who was once considered Khan's rival, said Abdul Qadeer Khan's work was a kind deed.
