Peshawar (AFP) — A Pakistan police officer travelling to guard polio vaccinators was shot dead Monday, police said, on the first day of a nationwide immunization effort after a year of rising cases.

The officer was travelling to guard polio vaccinators in the area of Jamrud town in northwestern Khyber Pakhtunkhwa province when he was killed, local police official Zarmat Khan told AFP.

“Two motorcycle riders opened fire on him,” he said. “The constable died instantly at the scene.”

Pakistan and neighboring Afghanistan are the only countries where polio is endemic and militants have for decades targeted vaccination teams and their security escorts.

Pakistan reported at least 73 polio infections in 2024, a significant increase compared to just six cases in 2023.

The vaccination campaign which started on Monday is the first of the year and is due to last a week.

“Despite the incident, the polio vaccination drive in the area remains ongoing,” Khan said.

Abdul Hameed Afridi, another senior police official in the area, also confirmed details of the attack and said officers have “launched an investigation.”

No group immediately claimed responsibility, however Khyber Pakhtunkhwa — which neighbors Afghanistan — is a hive of militant activity.

The Pakistani Taliban are the most active group in the area.

Polio can easily be prevented by the oral administration of a few drops of vaccine, but scores of vaccination workers and their escorts have been killed over the years.

In the past, clerics falsely claimed that the vaccine contained pork or alcohol, declaring it forbidden for Muslims.

In more recent years the attacks have focused on vulnerable police escorts accompanying the vaccinators as they go door-to-door.

Last year, dozens of Pakistani policemen who accompany medical teams on campaigns went on strike after a string of militant attacks targeting them.

Pakistan has witnessed rising militant attacks since the Taliban returned to power in neighboring Afghanistan.

More than 1,600 people were killed in attacks in 2024 — the deadliest year in almost a decade — according to the Center for Research and Security Studies, an Islamabad-based analysis group.

Islamabad accuses Kabul’s new rulers of failing to rout militants organizing on Afghan soil, a charge the Taliban government routinely denies.
