PESHAWAR, Pakistan (AP) — Police say gunmen in Pakistan have shot dead a female polio worker and wounded another in the northwest, while assailants have gunned down three Shiite Muslims in the south.
No group immediately claimed responsibility for slaying the vaccination workers, who have become frequent targets of attacks.
Some Pakistani militants allege that polio workers are U.S. spies and that the vaccine makes people sterile.
Police officer Mushtaq Khan says the two women were attacked Tuesday in Kaggawala village where they went as part of a U.N.-backed anti-polio campaign.
Separately, police officer Najam Tareen says gunmen fired on a vehicle carrying a Shiite lawyer and two of his sons, killing them in the southern city of Karachi.
The megacity is a hotbed of sectarian violence, with Shiite professionals often targeted.
