As AI technology advances, new image generator apps pop up all the time. Some of these can be used to make deepfake pornography where someone’s face is stitched onto an image of a naked body. Pictures of faces are often taken from social media profiles and used without consent.

It’s not just deepfake porn that’s a worry though - fake videos can be made of almost anything. The BBC’s Noor Nanji explains how Bollywood actresses are being targeted in this way.

And Dr Kerry McInerney and Dr Eleanor Drage from Cambridge University and the Good Robot podcast tell us about their biggest concerns around AI. What do tech companies need to do to protect people?

It’s been over two months since Hamas attacked Israel. The war between both sides has continued since then, with a temporary ceasefire and pauses in fighting in recent weeks. The BBC’s International Editor Jeremy Bowen, who has been covering the Middle East for nearly 30 years, gives us his analysis on how the war could end.

One challenge for Israel is Hamas’s network of tunnels, where its leaders are thought to be hiding. It’s believed to run for hundreds of miles, under most of Gaza. Jeremy is one of few BBC journalists who has been inside the tunnels, several years ago. He describes what they’re like and why they’re so important in this conflict.

The head of the United Nations agency for Palestinian refugees recently described Gaza as “hell on earth”. Hisham Mhanna from the ICRC tells us what it’s like in Southern Gaza right now, and the BBC’s Sally Nabil in Cairo explains the challenges getting aid across the border.
