Polio cases reported in Pakistan

Health officials say 13 cases of polio have been confirmed in Pakistan's volatile Swat District over the past four months, mainly because vaccinators have been unable to access children there for over a year. Fierce fighting between government troops and Taliban militants, which began in May, has displaced hundreds of thousands of people from Swat. Before the army campaign in the area which ended in July, militants had prevented access for anti-polio teams.
