Thrilled to share our latest with @thodsm.bsky.social: From Myanmar to the Sahel, from the Middle East to the DRC, civilians organize in self-defence groups and ‘militias’, take up arms to defend their villages. Who is responsible, and are their members combatants? blogs.icrc.org/law-and-poli...

In recent wars, hacker groups have targeted civilian infrastructure – from transport, to banks, to connectivity, to courts, and local governments. In 2023, the @icrc.org published ‘8 Rules for Hackers’, based on #IHL. Here is what they mean: www.youtube.com/watch?v=T2hl...

I agree and disagree: interesting blog on how non-humanitarian arguments can by used to achieve restraint by armed groups! But in the end, such strategies are not alternatives to #IHL; they must be used to achieve the same humanitarian goals! www.armedgroups-internationallaw.org/2025/05/28/p...

How is tech changing the battlefield, today and tomorrow? One trend that worries me: less human involvement through autonomous systems, but more civilian involvement through ‘Total Defence’ strategies. Read my @icrc.org colleague @2eatsoup.bsky.social info.icrc.org/e3t/Ctc/WY+1...
