Flies, mosquitoes swarm  Karachi

KARACHI: Swarms of flies are descending on  Pakistan’s commercial capital in what residents say are record numbers this rainy season, adding to the misery of Karachi’s monsoon “hell” and possibly bringing deadly diseases like malaria and dysentery.

Heavy rains have inundated the sprawling port city of nearly 20 million people for weeks, overwhelming shoddy drainage systems clogged with mountains of uncollected garbage and flooding neighborhoods with raw sewage.
