Covert drone strikes in war-torn Yemen leave more than just physical footprints. Using large-scale data analysis and anomaly detection techniques, researchers uncover surprising disruptions to civilian communication patterns after attacks.

* Data & Methods: Analyzed massive volumes of anonymized mobile phone metadata from Yemen, tracking changes following drone strikes.

* Key Findings: Drone strikes cause significant but localized spikes in communication activity—both calls and messages—in the immediate aftermath. These communications drop sharply afterward, suggesting disruption rather than solely increased discussion.

* Why It Matters: The findings challenge the perception of drone warfare as purely surgical by demonstrating its unintended impact on civilian daily life through big data analysis. This highlights a broader issue in modern covert conflicts.
