KABUL, Jan 20 (Reuters) - In the dull glow of a single bulb lighting their tent on the outskirts of Kabul, Samiullah and his wife Bibi Rehana sit down to dry bread and tea, their only meal of the day, accompanied by their five children and three-month-old grandchild.

"We have reached a point where we are content with death," said 55-year-old Samiullah, whose family, including two older sons aged 18 and 20 and their wives, is among the millions deported by neighbouring Iran and Pakistan in the past year.
