KASUR, Pakistan (Reuters) -When floodwaters from across the Indian border surged into her village in eastern Pakistan this month, Shama knew what to do: gather her four children and prepare to leave. It was the second time this year she has had to flee, after abandoning her home during cross-border fighting between India and Pakistan in May. Shama’s ordeal is echoed across flood-hit Kasur, where families say they are exhausted by repeated displacements within months, first from the fighting, now from nature.
