Missing Nida Naseer: Family's emotional video appeal
The family of teenager Nida Naseer have made an emotional video appeal for her to get in touch on the day before her 19th birthday.
The 18-year-old has not been seen since she went to put out the bins at her home in Pill, Newport, on 28 December.
Despite numerous appeals and police searches Nida has not been found.
Mr Tahir said: "It's more than three weeks and we have still not found any clue about Nida and we are very worried about Nida, Nida's safety, and we are appealing again and again.
"If anyone knows about Nida, tell us. We just want [her to] come back - we are missing you Nida. Nida if you are listening, Nida come back, Nida we want you... we want you in any condition.
"Nida come back - your family love you. Nida please come back."
'All worried about you'
In a second video, her sister Shamyla Naseer repeatedly appeals for Nida to come home, as her mother Najma Tahir sobs alongside her.
Ms Naseer says: "It's been more than three weeks. Nida, if you are listening to me, please come back home. Nida, we are all missing you - we are all worried about you.
"We all love you, we all need you, Nida. Everyone is worried about you. We can't live without you.
"Please come back home. Don't worry about anything. We are here for you, Nida."
Pakistan-born Nida was not wearing shoes and did not have her phone, money or coat with her when she disappeared.
Nida's family sought asylum after coming to the UK from Pakistan five years ago. Their application was turned down a year ago and they are currently appealing.
They believe Nida vanished because their asylum-seeker status prevented her from attending university, where she planned to study marketing or finance.
Her family has previously said marriage "was not an issue" and said the teenager did not have a history of depression or self harm.
Extensive police searches have been carried out in areas around the Transporter Bridge and George Street Bridge in Newport.
They have also searched land near the Lysaght Institute, and Pill Millennium Centre.
Nida was last seen wearing jeans and a black top. She has long dark hair, is slim and 5ft 3in (1.6m) tall.
Anyone with information is asked to contact Gwent Police on 101.
