Gave the article a read. It seems to heavily feature a "Horia Mosadiq": a feminist grifter who is apart of the Women' Regional Network, an organisation that pushes feminist, and sometimes LGBT, initiatives on countries such as Afghanistan, Zimbabwe and Pakistan.
One might even call this Mosadiq a collaborator. Here she is trying to point the British military towards advancing women's causes, and suggesting this may even help their war effort(ironically showing how feminist narratives and the war are intrinsically linked)
"Many Afghans tell Amnesty that they support the presence of international troops as long as they're there to help protect their human rights and improve their lives. The UK government should take this seriously, incorporating human rights benchmarks into its Afghanistan strategy.
Doing so will provide desperately needed assistance to millions of Afghans, particularly women, who still suffer terrible human rights abuses. It will also assist in the military effort and the job of protecting the UK's national security."
So when a woman like this, and those like her, mention unnamed witnesses, I've no reason to believe them since it's clear they seek to advance a nefarious agenda.
