The Pakistani government has postponed a polio vaccine program in parts of its tribal areas after threats from the Taliban.
Regional Taliban groups in North Waziristan and South Waziristan imposed a "ban" on the antipolio campaign to protest U.S. drone strikes.
Hafiz Gul Bahadur, the Taliban leader in North Waziristan, said the ban would remain until U.S. drone strikes are stopped.
Local officials said the Taliban action puts at risk the health of more than 350,000 children.
AFP reports a planned meeting of elders in Miranshah, North Waziristan to discuss the ban was called off due to a military curfew.
Last year Pakistan recorded its highest number of polio cases in a decade -- 198 -- which was blamed on a breakdown in its vaccination program.
