According to reports, local militants had abducted the vaccination worker, two local tribal policemen and a driver in Zhob district on Saturday.
“Security agencies conducted several operations to recover the polio worker and other team members and finally found their bodies in the mountains on Tuesday,” a senior local administration official in Zhob, Nazar Muhammad Khatran, told AFP.
He said it seemed the four men were shot dead on Saturday or Sunday.
A spokesman for the paramilitary Frontier Corps, Manzoor Ahmad, confirmed the incident.
Taliban militants claim that the polio vaccination drive is a front for espionage or a conspiracy to sterilize Muslims. They stepped up their attacks after a Pakistani doctor was recruited by the CIA to take part in a fake immunization drive to capture Osama Bin Laden.
Ahmad said Frontier Corps troops on Wednesday secured the safe release of five field staff from the Pakistan Telecommunication Company after an exchange of fire with militants in Zhob district. They had been abducted last week. -AFP
