A former intern at Britain's Government Communications Headquarters (GCHQ) has admitted to taking top-secret data home with him. The individual, whose identity was not disclosed, worked at the intelligence agency's headquarters in Cheltenham and accessed sensitive information without permission. He took the classified documents home with him and did not attempt to sell or share them.

A federal judge ordered senior Trump officials to preserve a group chat on military strikes in Yemen after a report revealed they potentially shared classified information. The chat was held on the Signal messaging app and discussed sensitive topics, including a strike against the Houthi rebel group. The order stems from a lawsuit filed by American Oversight, which alleges that Trump officials' use of Signal violated federal records laws.

Four lingering questions about Trump officials' Signal chat remain unanswered: why President Donald Trump's national security team was sharing sensitive information on an unsecure platform, how journalist Jeffrey Goldberg was added to the group chat, what kind of sensitive information was shared, and whether the administration's claims that no classified information was discussed are accurate.

The lives of British servicemen and women have not been put at risk by a major security breach in the United States, according to UK armed forces minister Luke Pollard. The breach occurred when a US journalist was added to a secret group chat where senior US officials discussed plans for a strike against the Houthi group in Yemen. Despite the leak, Pollard has "high confidence" that British operational security remains intact and that measures are in place to safeguard information.
