What we know about the new search for Madeleine McCann
New search for Madeleine McCann gets underway in Portugal
Police are searching derelict farm buildings in Portugal for evidence related to Madeleine McCann's disappearance 18 years ago.
The search is focused on an area near a cottage where Christian Brueckner, the prime suspect, used to live.
Investigators are acting on a reported tip-off, hoping to find Madeleine's body or clothing, using tools like shovels, pickaxes, and ground-penetrating radar.
Christian Brueckner, a German national, is the main suspect but denies involvement; he is due to be released from prison in September after serving time for a rape conviction.
Madeleine's parents have vowed to continue their search for answers, marking the 18th anniversary of her disappearance and what would have been her 22nd birthday.
