Ukraine's southern defence forces formally rejected Russian allegations, denying Ukrainian troops struck the ZAPORIZHZHIA NUCLEAR PLANT transport workshop and calling the claims baseless.

At the Shangri-La Dialogue (May 29-31 in Singapore), UK Defence Secretary John Healey said the UK will work with the United States and Australia under the trilateral security partnership to jointly develop new weapons for unmanned submersibles. The UK will allocate £150m (about $200m) to the project. The announcement builds on the 2021 AUKUS pact, under which the US and UK agreed to help Australia build nuclear-powered submarines—a move that has prompted regional concern; the IAEA warned it could set a dangerous precedent and trigger a chain reaction.

IDF says preliminary reports indicate alerts were triggered for suspected hostile aircraft penetration near Rosh Hanikra.
