For large numbers of Bangladeshi and Rohingiya women, its a journey to hell. A journey that begins from home - the borders of lower Myanmar and Bangladesh - and culminates in the festering ghettos of Karachi and other Pakistani cities. In officialese this is subcontinental illegal human trafficking, although calling it plain slave trade would be a better description. Once in Pakistan, the price of a female illegal migrant ranges from $1,285 to $2,428, depending on her physical attributes and conditioning. Harassed, tortured, exploited and abused every step of the longest refugee trail in Asia, only the lucky ones die young.
