The assailants fled the scene and no one immediately claimed responsibility for the attack in the town of Gomal PESHAWAR, Pakistan: Gunmen riding on motorcycles opened fire on Tuesday on police escorting a team of polio workers in northwestern Pakistan, killing two policemen, authorities said. None of the polio workers were harmed, said Mohammad Imran, a local police official. The four polio workers and their police escort were all traveling on motorcycles. The assailants fled the scene and no one immediately claimed responsibility for the attack in the town of Gomal, in Khyber Pakhtunkhwa province bordering Afghanistan. The attack came on the second day of Pakistan’s latest anti-polio campaign in the province. Pakistan has registered 14 new polio cases since April, all from Khyber Pakhtunkhwa province. The outbreak has been a blow to the Islamic nation’s efforts to eradicate the disease, which can cause severe paralysis in children. Pakistan’s anti-polio campaigns are regularly marked by violence as Islamic militants often target polio teams and police protecting them, falsely claiming that the vaccination campaigns are a Western conspiracy to sterilize children. Pakistan and Afghanistan are the only countries in the world where polio remains endemic. In 2021, Pakistan reported only one case, raising hopes it was close to eradicating polio.
