McCanns Encouraged By New Madeleine Search
Kate and Gerry McCann say they are "encouraged by the progress" being made by search teams in Portugal close to where their daughter Madeleine went missing.
Writing on their Official Find Madeleine Campaign Facebook page, the couple said: "We are kept updated on the ongoing work in Portugal and are encouraged by the progress.
"Thank you for continuing to stand by us and supporting our efforts to get Madeleine home."
Police searching an area of scrubland in Praia da Luz have begun looking inside drains for any clues about her disappearance.
At least three manhole covers were pulled up and mini cameras dropped into underground pipes, on the fourth day of the search by officers from Britain.
Sniffer dogs started hunting for evidence at first light, scouring areas within the police cordon that had not previously been explored.
Officers have also been using ground-penetrating radar to discover whether anything may be buried there.
The large search zone in the Portuguese resort lies on unused land, five minutes' walk from the holiday complex where the McCanns were staying in May 2007.
Officers had planned to search the area only until Friday but have asked authorities in Portugal for an extra week.
Tents have been put up at several locations, including one above a hole concealed by corrugated iron which was exposed on Tuesday when trees and shrubs were cut down.
Forensics officers dressed in white overalls were seen coming and going from the tents, pushing wheelbarrows around the site and using large sieves to sift through soil for clues.
Evidence bags were carried away as Detective Chief Inspector Andy Redwood, who is leading the investigation, looked on.
Police have not spoken about the intelligence that led them to the scrubland, which is thought to be one of three sites of interest in Praia da Luz.
Madeleine was three years old when she disappeared from the Algarve resort while on holiday with her parents, Kate and Gerry McCann, and her younger siblings.
The renewed search for the missing youngster is a joint effort between police in the United Kingdom and Portugal and follows a Metropolitan Police review of the seven-year-old case.
Officers are expected to be given more time to search the site, which is guarded by local police day and night.
It is not clear whether work will continue over the weekend, while no activity is expected on Tuesday as it is a public holiday in Portugal.
