Portuguese and German police have initiated a significant new search operation for Madeleine McCann, the British toddler who disappeared in 2007. The search is focused on a vast area in the Algarve region, specifically near Praia da Luz, where she was last seen. Investigators are scouring abandoned structures and nearby scrubland, aiming to uncover new evidence in the case that has remained unsolved for over 18 years. This renewed effort follows recent developments and a tip-off that could potentially provide crucial insights into the investigation.
