Three sensitive messages from full Signal chat explained

In his message, Waltz congratulates Pete - referring to Hegseth, as well as the IC, shorthand for "intelligence community" and Kurilla, a reference to Michael Kurilla, a US Army General who oversees Central Command, a regional combatant command with responsibility over the Middle East and parts of Central and South Asia. The messages do not reveal how the target's whereabouts or movements were tracked. A military expert contacted by the BBC - but who wished to rename nameless - suggested that a combination of aerial platforms, technological tracking capabilities or human intelligence on the ground could have been used, or a combination of various sources. At least 53 people were killed in the initial wave of US airstrikes on Houthi targets in Yemen, which struck more than 30 targets including training facilities, drone infrastructure, as well as weapons manufacturing and storage sties and command and control centres, including one in which the Pentagon said several unmanned aerial vehicle experts were located. It is unclear which of the targets Waltz was referring to in the group chat.
