Via The Wall Street Journal: Polio Workers Killed in Pakistan. Excerpt:
Three members of polio vaccination teams were shot dead Tuesday in the southern city of Karachi, in the latest attack by Islamic militants on health workers trying to inoculate children against the crippling disease.
At least two other health workers were injured when gunmen on motorbikes opened fire in the city's southern Qayuumabad residential area—close to the city center.
"There were four men on two motor bikes armed with pistols," said Raja Umar Khattab, a senior investigator with the police's antiterrorist Crime Investigation Department unit.
Militants have repeatedly targeted polio workers, accusing them of spying for the West, though the main Tehreek-e-Taliban Pakistan insurgent group claims it doesn't order the killings.
Hospital officials in Karachi said that the dead were two women and a man.
Police officials had said that the polio workers were on foot and had started their door to door visits when the attack took place.
It is unclear why the polio teams didn't have police protection with them. After a number of attacks on polio workers, the vaccination teams are now supposed to go out only with police protection.
Pakistan President Mamnoon Hussain has condemned the attack, which came hours before he was to officially inaugurate the polio campaign in the capital Islamabad.
Before Tuesday's attack, at least 29 people working in polio teams had been killed since mid-2012, with attacks across the country.
Both health workers and security personnel deployed for their protection have been targeted.
