Photos: Hundreds of Stray Dogs Poisoned in Pakistan

Officials have poisoned hundreds of dogs in Karachi, Pakistan in the latest effort to curb a population of strays that attack thousands of people each day. Bodies of dead dogs are seen littered around the city as municipal workers gathered them for disposal.

Officials estimated the operation had culled thousands of strays but did not have a full accounting for all six city districts.

"At least 700 dogs have been killed only in two areas of Karachi's south in the couple of days," said Sattar Javed, a spokesman for the municipal authority.

The periodic culling of stray dogs using poison tablets hidden in chicken has drawn criticism from animal rights activists but a city official, Mohammad Zahid, said it was necessary because packs of strays posed a threat to residents.
