Vaccine teams and security forces escorting them are often targeted in attacks in Pakistan, one of three countries where the crippling disease remains. The Taliban claims the preventive drug is a Western conspiracy to sterilise children.
Gunmen in Pakistan shot and killed two policemen on Wednesday who were part of the most recent anti-polio drive in the country's rugged northwest, officials said.
The gunmen opened fire as the policemen were heading on foot to the town of Lower Dir in the Khyber Pakhtunkhwa province bordering Afghanistan, local police official Saeedur Rehman said. He said the attackers fled the scene and that a search was under way to find them.
The policemen were to escort a team of medics going house-to-house to vaccinate children against the crippling disease. No one immediately claimed responsibility for the shooting.
Pakistan –– one of three countries in the world unable to get rid of the virus –– regularly carries out anti-polio drives despite threats from the Taliban, which claims the campaign is a Western conspiracy to sterilise children. Polio teams and security forces escorting them are often targeted in deadly attacks.
The latest three-day anti-polio campaign started on Monday.
Rehman said that despite Wednesday's attack, the teams would carry on administering polio drops to children in Lower Dir till the end of the day.
So far this year, 94 new polio cases have been reported in Pakistan, compared with only 12 in 2018.
Authorities say the increase in polio cases was mainly because of the parents' refusal to let their children be vaccinated.
Prime Minister Imran Khan's government has deployed additional police forces to guard polio teams and has appealed, with the support of clerics, on the parents to allow their children to get polio drops.
The latest anti-polio campaign was to include 39.5 million children up to five years of age across the entire country. Pakistan has an estimated population of 220 million.
Polio is also endemic in Afghanistan and Nigeria.
