Suspected militants opened fire on a vehicle carrying police officers assigned to protect polio workers in northwestern Pakistan on Tuesday, killing one of them and wounding four others before fleeing the secene, police said. Two attackers were killed when police returned fire.
The shooting occurred in Hangu, a district in Khyber Pakhtunkhwa province bordering Afghanistan, shortly after Pakistan launched its second nationwide anti-polio campaign of the year, according to local police official Mahmood Alam.
