Unidentified gunmen opened fire on a polio team on Saturday in Pakistan’s Khyber, killing one person, even as there was no word on a two-member team with two police escorts, that went missing a day before. The driver of the vehicle was killed, a media report said. The missing team was headed for a remote area in Balochistan. “Two polio workers, escorted by two constables of the Balochistan levies, left the district headquarters at 11 pm on Friday to vaccinate children in the Murgha Gibzai area of Zohab district but they have not reached their destination,” Pakistan Today quoted Zhob Deputy Commissioner Nazir Ahmed Khetran.
