Islamabad, Nov 24 (IANS): A polio vaccination team, accompanied by policemen, was attacked in Pakistan Monday while administrating polio vaccination drops to children, media reported.

At least one person was injured when the attack took place in Charsadda district in the Khyber Pakhtunkhwa province, Dawn online reported.

Northwestern Pakistan has seen scores of incidents where polio vaccination teams were attacked.

The Federally Administered Tribal Agencies (FATA), which has never been able to vaccinate its targeted population of around nine million since the global polio eradication initiative began in Pakistan in the mid-1990s, has become a real challenge for the government and UN agencies. They are finding it extremely hard to address the issue of reaching unvaccinated children and tackle vaccination refusal cases.

The World Health Organization (WHO) has said that Pakistan is responsible for nearly 80 per cent of polio cases reported globally.
