No one has claimed responsibility, but Pakistan's anti-polio campaigns are regularly marked by violence. Islamic militants often target polio teams and police assigned to protect them, falsely claiming that the vaccination campaigns are a Western conspiracy to sterilise children.
Since January, Pakistan has reported only one polio case, raising hopes that the country is close to eradicating the disease.
Pakistan and Afghanistan are the last two countries in which polio has not been eliminated.
