Grisly attacks in Pakistan target those doing good to children (Polio vaccination)

As reported in The Economist in the Dec 22 2012 print edition:

ON DECEMBER 18th five health workers, all women, were gunned down in Pakistan in carefully planned and co-ordinated shootings. They were administering polio vaccinations. The following day a vaccination supervisor and her driver were killed. Several health workers are critically injured. The youngest killed was a 17-year-old in the north-western town of Peshawar. Others were working in poor, ethnic Pushtun districts in the southern megacity of Karachi, where polio workers have already been killed this year. The Pakistani Taliban or allied groups are the murderers, and they have now caused the UN to suspend its campaign to eradicate polio in Pakistan. For more information, click here
