In a former classroom, now a makeshift relief camp, pregnant women take refuge from the floods that have ravaged eastern Pakistan, their bodies aching, eyes heavy with exhaustion and silent despair.

Shumaila Riaz, 19 years old and seven months pregnant with her first child, spent the past four days in the relief camp, enduring pregnancy cramps.
