Advancing #IHL implementation took centre stage, with representatives from across Africa highlighting the crucial role of the National IHL Committees. These committees can help turn IHL obligations into national action, strengthen coordination and promote its respect. #GIIHL

Two days of discussions with representatives from across East, South & West Africa gave us valuable insights into how National IHL Committees can support the implementation of #GIIHL. Glad to have been part of these worthwhile discussions and this important exchange.

The International Committee of the Red Cross is an important partner in advancing global humanitarian efforts, particularly in protecting vulnerable communities and supporting people in need. We will continue working closely with the ICRC to deepen our partnership and strengthen humanitarian efforts in Kenya and beyond. We are glad to host the ICRC as it seeks to establish a global operations centre in our country. Met President of the International Committee of the Red Cross Mirjana Spoljaric on the sidelines of the United Nations General Assembly in New York.

On the International Day of Peace, we are reminded that how wars are fought matters for the people living through them, and for what becomes possible when the fighting ends. By protecting civilians and setting limits on the means and methods of warfare, international humanitarian law helps reduce harm and keep open the possibility of recovery, reconciliation and peace.

Millions of people worldwide are forced to flee their homes due to armed conflict, other violence, disasters, or human rights violations, yet remain within their own country’s borders. They are known as internally displaced persons (IDPs). On this anniversary of the Guiding Principles on Internal Displacement, we highlight the importance of strengthening protection for everyone affected by displacement as a consequence of conflict or violence.

📣 New blog out, co-authored with @ICRC Vanessa Murphy – the main drafter and driving force behind this one!   Is ENMOD — the 1977 treaty prohibiting hostile environmental modification techniques — a Cold War relic or a sleeping giant? We make the case for the latter. 🧵

Science and technology have caught up: weaponizing environmental modification capabilities is now more likely than ever. At the same time, the natural environment is increasingly fragile. Time for more States to take ENMOD seriously 👉🏽 opiniojuris.org/2026/03/18/e… @UN_Disarmament

The movement of millions of people each year along risky routes is often linked to armed conflicts. Many migrants are caught in wars at different stages of their journey. Respect for #ihl improves protection for all civilians, including migrants. More ➡️ international-review.icrc.or…
