The United Nations is pushing the Islamic Emirate of Afghanistan (IEA) administration for more exemptions to its ban on most female aid workers, top U.N. officials said on Wednesday, while also expressing concern that foreign women working for international organizations and embassies could next be targeted.

Speaking to Reuters during a visit to Kabul, U.N. aid chief Martin Griffiths said that his message during meetings with Taliban officials had been: "If you can't help us rescind the ban, give us the exemptions to allow women to operate."

Last month, the IEA - who seized power in August 2021 - banned most female aid workers and stopped women from attending university after stopping girls from attending high school in March. Griffiths traveled to Afghanistan after a visit last week by U.N. Deputy Secretary-General Amina Mohammed.

Griffiths said some exemptions to the female aid worker ban had been granted in health and education and that there were indications there could be a possible exemption in agriculture. But he said much more was needed, with nutrition and water and sanitation services a priority to prevent severe illnesses and malnutrition during a severe humanitarian crisis in Afghanistan, Reuters reported.

"We have not seen the history of the Taliban (IEA) reversing any edict. What we have seen is exemptions that, hopefully, if we keep pushing them, they will water down those edicts to a point where we will get women and girls back into school and into the workplace," Mohammed told reporters in New York on Wednesday.

Griffiths told Reuters that, following his recent discussions with the IEA, he was hopeful they would create a set of written guidelines to allow aid groups to operate with female staff in more areas with certainty in coming weeks.

"The next few weeks are absolutely crucial to see if the humanitarian community ... can stay and deliver," he said, while cautioning: "I don't want to speculate as to whether we're going to come out of this in the right place."

The IEA did not immediately respond to a request for comment on its plans over guidelines.

During her visit last week, Mohammed met with the Shura - the leadership council that issues the bans - in the southern Taliban heartland of Kandahar. She said there is a concern that they may next prohibit "international women from international organizations and embassies."

"It hasn't happened so far," said Mohammed, adding that they had been expecting a possible announcement all month. "I don't say that it won't, but clearly the pressure that we're putting on has stopped that rollback as quickly."

Griffiths said the United Nations would continue operating in Afghanistan wherever it could, but there was a concern that international donors might not want to commit to the huge financial cost of aid at around $4.6 billion a year.

"I lose sleep about this, I really do," Griffiths said, adding that he would meet with donors in coming weeks to make the case for why Afghanistan needed help during an intense humanitarian crisis in which 28 million people were in need of aid, including 6 million on the brink of famine.
