A body found by police in Malaysia has been confirmed as that of missing teenage girl Nora Quoirin, a trust helping with the search announced on Tuesday.

"The Lucie Blackman Trust can confirm with great sadness that the body found today is that of missing teenager Nora Quoirin," the charity said in a statement.

The body was found earlier in the day near a stream some 2.5 km away from the resort the family had been staying in for a holiday. It was then airlifted to hospital for identification.

Nora Quoirin, a 15-year-old with learning difficulties whose family home is in London, disappeared on August 4 from her room at the Dusum resort in Seremban, about 70 km south of Malaysia's capital Kuala Lumpur.

On Monday, her family had offered a 50,000 Malaysia Ringgit (€10,600) reward "for information leading to the return of their daughter". The money had been donated "by an anonymous Belfast business," according to a statement.

"Nora is our first child. She has been vulnerable since the day she was born. She is so precious to us and our hearts are breaking," the family also said in the statement.

Two crowdfunding appeals had been launched to help in the search, one by Nora's Irish aunt, Aisling Agnew and another by Pacome Quoirin, her French uncle.

Both wrote that because of her learning and development disabilities, "Nora would not know how to get help and would never leave her family voluntarily."

Local police deployed a significant search and rescue operation to find the young girl including more than 350 officers as well as helicopters and drones. Reuters news agency also reported that two shamans had joined in the search.

France's Foreign Ministry said in a statement on Tuesday that it has learnt of the passing of Nora "with great sadness."

"We wish to express our sincere condolences to her family and loved ones and assure them of our profound compassion," it added, thanking local authorities and the Malaysian people for their "solidarity".

Irish Foreign Minister Simon Coveney had said earlier in the day that Irish and French embassies in Malaysia were "working together to provide every assistance to the Quoirin family."
