PESHAWAR, Pakistan (AP) - Pakistani police say gunmen have killed two anti-polio workers in northwest Pakistan.
Swabi District Police Chief Mohammad Saeed says the two Pakistani health workers were killed Sunday while on a vaccination drive in Kandar village.
He says gunmen arrived on foot and later disappeared.
Pakistan is one of the world's few remaining countries, along with Afghanistan and Nigeria, still affected by the polio virus.
As many as 58 cases were reported in Pakistan in 2012, down from 198 in 2011.
Over the past year, attackers have killed several health workers from Pakistan's anti-polio campaign.
Pakistani militant groups oppose the vaccinations and accuse the workers of spying for Washington.
The killings came a day after a Pakistani al-Qaida-linked militant group, Lashkar-e-Jhangvi, killed 24 people in the southwestern city of Quetta.
