A Pakistani hospital worker ties together the toes of Madiha Bibi, a polio worker killed by unknown gunmen, at the morgue of a local hospital in Karachi, Pakistan, Tuesday, Dec. 18, 2012. Gunmen killed several people working on a government polio vaccination campaign in two different Pakistani cities on Tuesday, officials said. The attacks were likely an attempt by the Taliban to counter an initiative the militant group has long opposed. (AP Photo/Fareed Khan) less
