Multiple police officers have been killed and many others injured in a bomb explosion targeting their vehicle during a polio vaccination campaign in northwestern Pakistan. The blast occurred in Bajaur, a tribal district in Khyber Pakhtunkhwa province bordering Afghanistan, on the first day of the vaccination drive. Some of the injured officers are in critical condition and have been transferred to a hospital in the provincial capital, Peshawar. The Tehreek-e-Taliban Pakistan (TTP) has claimed responsibility for the attack, continuing their pattern of targeting security forces and vaccination workers.

The group has been responsible for killing numerous polio vaccination workers and officers in recent years. Resistance to the polio vaccination campaign has been fueled by concerns sowed by religious leaders, who have spread misinformation regarding the content of the vaccine, and by the CIA's use of a fake vaccination drive to track Osama bin Laden in 2011.

Despite these challenges, Pakistan and Afghanistan have made progress in reducing polio cases, reporting only six cases each in 2023, a significant decrease from previous years. However, the recent attack has led to the suspension of the vaccination campaign in the Bajaur region. This incident highlights the ongoing threat to anti-polio efforts and the challenges faced in eradicating the disease in the region.
