This week Friday May 25, was International Missing Children's Day - a day where people around the world commemorate the missing children who have found their way home, remember those who have been victims of crime, and continue efforts to find those who are still missing.
The main purpose of International Missing Children's Day is to encourage everyone to think about children who remain missing and to spread a message of hope.
To mark the event, The Sun, on Friday, told how a child disappears every three minutes in Britain. The Sun's ANTONELLA LAZZERI spoke to Dr Safraz Khan - whose six-year-old daughter Aamina is missing - about his ordeal.
SCRAWLED in her tiny hand, Aamina's letter tells her dad how much she loves him, the fun they have and includes a picture of them playing.
A few weeks after she wrote the note, six-year-old Aamina Khan was abducted by her mother and taken to Pakistan.
Yesterday her father Dr Safraz Khan sobbed as he said: "I haven't seen my baby for nine months. I'm living in hell. It has destroyed me.
"Just before she went missing we had been decorating her bedroom together. She had chosen the things she wanted.
"Now it's all there but she isn't. Every day I feel like I can't go on, the pain is incredible. But I won't give up on my daughter. She is everything to me."
Dr Khan, 43, a scientist from Croydon, south London, had custody of his daughter after splitting from wife Humma, 38, a doctor, in 2006. He said: "From the moment she was born I doted on Aamina. Her cot was on my side of the bed and I would get up in the night to feed her. We were inseparable."
Her mother had regular contact with Aamina. They vanished after Dr Khan handed his daughter over during the summer holidays last year.
He said: "The last day I saw my daughter was August 20. She gave me a huge hug and kiss and said, 'Papa, don't forget to pick me up on September 5'. "
Breaking down, he added: "I took a long look at her and drove away. I haven't seen her since. It's just unbearable, I love my daughter so much. The fear of never seeing her again just kills me."
When he went to pick up Aamina, he found his ex-wife's home dark and her car gone.
He said: "I was frantic. I tried phoning her but there was no answer. I immediately phoned the police."
The following day officers told him his ex-wife had got Aamina a Pakistani passport and flown there with her.
Dr Khan has since been to the country three times looking for his daughter. He welcomes the missingkids website, on which Aamina is featured. He said: "It's vital that information is circulated worldwide.
"My only hope of getting Aamina back is if someone spots her and calls police."
