PESHAWAR: More than 100 police who provide security for polio vaccination teams in restive border areas went on strike on Thursday after a string of deadly militant attacks this week.

Police officers who are routinely deployed to protect polio workers going door-to-door frequently come under attack by militants waging a war against security forces.

Hundreds of police and polio workers have been killed over the past decade.

"Police officers will not perform polio duties," a police official participating in the protest, who did not want to be identified, told AFP.

"If necessary, army and border troops should be deployed alongside the police to protect polio teams so they can understand how difficult this task is," the official said.

Another officer said negotiations had failed between the protesting police in Bannu district, in the northwestern border province of Khyber Pakhtunkhwa, and senior officials.

"Any constable who learns of the protest is leaving their polio duty to join the demonstration," the second officer told AFP.

At least two police officers and one polio worker have been shot dead in separate attacks in rural districts near the border with Afghanistan since the launch of the latest vaccination drive on Monday, including one officer escorting a team on Thursday.

Nine people were also wounded on Monday in a bomb attack on a polio vaccination team. Most attacks are claimed by the Pakistani Taliban, a separate group from the Afghan Taliban.

Polio and militancy surge

The country has seen a surge in polio cases this year, recording 17 so far in 2024, compared with six in 2023. Health officials had aimed to vaccinate 30 million children in a week-long campaign.

"Due to the police strike, around 5,000 children have missed their vaccinations and alternative arrangements are being made to cover them," a government official in Khyber Pakhtunkhwa province’s capital told AFP on condition of anonymity because he was not authorised to speak to the media.

According to the United Nations children’s agency (UNICEF), the number of polio cases in Pakistan has fallen dramatically from around 20,000 annually in the early 1990s.

Pakistan has witnessed a surge in militant attacks since the Taliban government returned to power in neighbouring Afghanistan in 2021, mostly in the KP but also in southwestern Balochistan, which abuts Afghanistan and Iran.

Islamabad accuses Kabul’s rulers of failing to root out militants sheltering on Afghan soil as they prepare to stage assaults on Pakistan.
