Search teams have been seen draining a well and clearing areas of dense vegetation near abandoned buildings as the latest search for missing British girl Madeleine McCann continues in Portugal.
German investigators along with Portuguese police officers and firefighters are working in a little-developed area of countryside a few miles from Praia da Luz where Madeleine was last seen in 2007.
Then aged three, she vanished while on holiday with her family in the Algarve resort after her parents went out to dinner and left her sleeping in a room with her toddler twin siblings.
Journalists were being kept a distance away from the search sites today and a no-fly zone was imposed that stopped the use of drones, although some activity at the site could be seen as teams used strimmers, pick-axes, shovels and chainsaws to clear the undergrowth and debris surrounding an abandoned building.
Personnel wore safety gear such as gloves and hard hats as they worked in the dense vegetation, and firefighters and police were seen using a yellow hose to drain a well.
TV footage showed Portuguese police officers guarding the end to a narrow lane that leads through an area of fields and scrubland with a few houses and a vineyard.
It has been variously reported that investigators will look where trenches were dug near the resort at the time of Madeleine's disappearance, at wells, ruins and water tanks, and that there are plans to examine 21 pieces of land.
The search is being carried out at the request of the German federal police as they look for evidence that could implicate prime suspect Christian Brueckner, who is in prison for raping a 72-year-old woman in Praia da Luz in 2005.
He is due to be released from jail in September if no further charges are brought.
In October last year, Brueckner was cleared by a German court of unrelated sexual offences alleged to have taken place in Portugal between 2000 and 2017.
Around 30 German police officers, including forensic experts, are expected to take part in the search along with Portuguese officers, with the activity due to last until Friday.
The Metropolitan Police said it is aware of the operation but that British officers will not be present.
German investigators and Portuguese officers last carried out searches in the country in 2023 near the Barragem do Arade reservoir, about 48km (30 miles) from Praia da Luz.
Brueckner, who spent time in the area between 2000 and 2017, had photographs and videos of himself near the reservoir.
It was previously searched in 2008, when Portuguese lawyer Marcos Aragao Correia paid for specialist divers to search it after he claimed to have been tipped off by criminal contacts that Madeleine's body was there.
British police were later given permission to examine scrubland, near where she vanished, in 2014.
Last month, Madeleine's family, who are from Leicestershire in England, marked the 18th anniversary of her disappearance, describing her as "beautiful and unique" before her 22nd birthday, and expressing their determination to keep searching.
A statement from her parents Kate and Gerry McCann and the family said: "The years appear to be passing even more quickly and whilst we have no significant news to share, our determination to 'leave no stone unturned' is unwavering. We will do our utmost to achieve this."
