Torkham, Afghanistan – Gul Khan Kaka was in his early 20s when he had to abandon his home and flee to neighbouring Pakistan after the Soviets invaded Afghanistan in 1979, a war that lasted a decade.
Four decades later, Kaka, now 62, is a refugee again – this time as an undocumented Afghan driven out of Pakistan as part of a government crackdown on “illegal” foreigners.
