Camilla was attending a Women in Journalism mentoring session and panel discussion at Dumfries House in Ayrshire.
“I’ve been reliably informed that in 2020, there were 700 female journalists working in Kabul Today, there are fewer than 100,” Camilla said.
“With the loss of 600 voices, the experiences of countless Afghans will remain untold.”
She added: “All journalists who fight for truth and justice in the face of retribution deserve our thanks and admiration.
“Let’s do all we can to support, promote and, crucially, listen to the brave female journalists of Afghanistan, whose work puts them in danger every single day.”
The duchess was joined by BBC journalist Yalda Hakim who received praised for conducting an interview with a Taliban spokesman when he called her phone while she was presenting live on air in the BBC studio.
Camilla said: “It’s been a particular pleasure to speak to Yalda Hakim, who recently interviewed a Taliban spokesman with such focus and composure.”
Founded by Eve Pollard 28 years ago, Women in Journalism is a not-for-profit organisation that provides guidance and support for its members.
Camilla and the Prince of Wales are carrying out engagements in Scotland this week.
