The Taliban are not the only threat to Afghanistan. Aid cuts could undo 20 years of progress

The most vulnerable people will bear the cost of sanctions, as services and the economy collapse

Watching Afghanistan's unfolding trauma, I've thought a lot about Mumtaz Ahmed, a young teacher I met a few years ago. Her family fled Kabul during Taliban rule in the late 1990s.

Raised as a refugee in Pakistan, Ahmed had defied the odds and made it to university. Now, she was back in Afghanistan teaching maths in a rural girls' school. I came back because I believe in education and I love my country," she told me. These girls have a right to learn - without education, Afghanistan has no future."
