Madeleine McCann: Police in Portugal search scrubland
Police investigating the disappearance of Madeleine McCann have sealed off a large area of scrubland in the Algarve resort of Praia da Luz.
The British girl was three when she went missing in the resort in 2007.
On 22 May Scotland Yard said a "substantial phase of operational activity" would start in Portugal in the coming weeks.
Sources in Portugal told the BBC that had now started, and police with dogs are at the scene.
