Kate and Gerry McCann have shared a heartfelt message to mark the 18th anniversary of their daughter Madeleine's disappearance.
The couple posted the emotional tribute on their Official Find Madeleine Campaign Facebook page on Friday evening, just hours before the milestone date of May 3.
Madeleine vanished during a family holiday in the resort of Praia da Luz on the Algarve in Portugal on May 3, 2007, when she was just three years old.
Despite no positive sightings over the past 18 years and no charges brought for her abduction, her parents have never given up hope of finding her.

In their message, the McCanns wrote: "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."
They also noted that May is Madeleine's birthday month, with her turning 22 this year.
"No matter how near or far she is, she continues to be right here with us, every day, but especially on her special day," they wrote.
"We continue to 'celebrate' her as the very beautiful and unique person she is. We miss her."
