A girl who was swept away in the Boxing Day tsunami in Indonesia almost 10 years ago has been reunited with her family, who had long believed she had perished in the 2004 disaster.

Raudhatul Jannah was four years old when the tsunami hit her home in West Aceh, carrying off her and her seven-year-old brother. Her parents spent a month searching for their children before giving up hope of ever finding the youngsters.

But recently the girl's uncle spotted Jannah walking home from school and was so moved by her resemblance to his missing niece that he made enquiries about her background.

He found that she had been rescued after the tsunami by a fisherman who gave her to his elderly mother to raise.

Jannah's parents visited the girl, who had been given the name Weni, in June and immediately knew she was their child, DPA reported.

"God has given us a miracle," Jannah's mother Jamaliah said. "My husband and I are very happy. I am so grateful to God for reuniting us with our child after 10 years of being separated."

"My heart beat so fast when I saw her," she added. "I hugged her and she hugged me back and felt so comfortable in my arms."

Jannah and her brother survived the tsunami by clinging onto a piece of wood and Jannah has told her parents that she believes her sibling could still be alive. The family are now preparing to search for him on the sparsely inhabited Banyak Island, where Jannah said they had been stranded.

Jamaliah said that she is in no doubt that Jannah is her daughter and is willing to undergo DNA tests.

The Indian Ocean tsunami killed 230,000 people in 14 countries.
