Three workers in a polio eradication campaign were shot in聽Pakistan聽on Wednesday, and two of them were killed, the latest in an unprecedented string of attacks over the past three days that has partially halted the UN-backed campaign.

The聽United Nations聽in聽Pakistan聽has pulled all staff involved in the campaign off the streets, spokesman聽Michael Coleman听蝉补颈诲.

The government said immunization was continuing in some areas without UN support although many workers refused to go out. Women health workers held protests in the southern city of聽Karachi聽and in the capital,聽Islamabad.

"We go out and risk our lives to save other people's children from being permanently handicapped, for what? So that our own children become orphans?" health worker聽Ambreen Bibi聽said at the聽Islamabad聽protest.

The government was caught off guard by the violence, saying they had not expected attacks in areas far from聽Taliban聽strongholds and they would have to change tactics in the health campaign.

"We didn't expect such attacks in聽Karachi," said Mustafa Nawaz Khokhar, minister for human rights, who oversees the polio campaign. He was referring to the southern commercial hub where there have been attacks this week.

"In far flung areas where the threats are more pronounced, we have been providing polio teams security."

Wednesday saw four separate attacks, all in the north. In the district of聽Charsadda, men on motorbikes shot dead a woman and her driver, police and health officials said.

Hours earlier, gunmen wounded a male health worker in the nearby provincial capital of Peshawar. He was in critical condition, said a doctor at the聽Lady Reading Hospital聽where he is being treated.

Four other women health workers were shot at but not hit in nearby Nowshera, said聽Jan Baz Afridi, deputy head of the Expanded Programme on Immunisation. Two women health workers were shot at in Dwasaro village in聽Charsadda, police said.

It was not clear who was behind the violence.

Many Islamists, including聽Taliban聽militants, have long opposed the campaign. Some say it aims to sterilize Muslims, while one militant commander said it could not continue unless attacks by U.S. drone aircraft stopped.

The聽Taliban聽have repeatedly threatened health workers involved in the campaign. Some said they received calls telling them to stop working with "infidels" just before the attacks.

But a spokesman for the Pakistani聽Taliban,聽Ihsanullah Ihsan, told Reuters his group was not involved in the violence.

'Better coordination'

On Monday and Tuesday, six health workers were killed in attacks in the southern port city of聽Karachi聽and in Peshawar. Five were women and the youngest was 17.

Five of the shootings happened in聽Karachi, home to 18 million people. Health authorities there suspended the polio eradication campaign in the entire province of聽Sindh.

Karachi police聽spokesman聽Imran Shaukat聽said teams were supposed to tell police of their movements but had not done so.

"There has to be better coordination between the health department and police," he said. "We have decided that we will be more forthcoming and contact polio team heads ourselves."

Minister Khokhar said the drive would resume as soon as security was in place.

"The teams go into every little neighbourhood. You can understand that enormous resources are needed if we have to protect each and every team and worker, which we will have to now," he said.

On Wednesday, police said they killed two people and arrested 15 during raids connected to the shootings.

Authorities in the northern聽Khyber Paktunkhwa聽province, the capital of which is Peshawar, said they would not accept the U.N.'s recommendation to suspend the campaign.

"If we stopped the campaign it would encourage the forces opposing the polio vaccination," said provincial official Javed Marwat.

But their insistence the campaign continue angered health workers who said their colleagues told officials inCharsadda聽about threats before Wednesday's shootings. The officials insisted the vaccinations take place anyway.

Khokar said聽Taliban聽hostility to the campaign increased after it emerged that the CIA had used a fake vaccination campaign to try to gather information about聽Osama bin Laden, before he was found and killed in a Pakistani town last year.

Pakistan聽had 20,000 polio cases in 1994 but vigorous vaccination efforts had brought the number down to 56 in 2012, the government said.

A global vaccination campaign has eradicated the disease from everywhere except聽Pakistan,聽Afghanistanand聽Nigeria.

Polio can paralyse or kill within hours of infection. It is transmitted person-to-person, meaning that as long as one child is infected, the disease can be passed to others.
