This is the heartwarming moment Nazanin Zaghari-Ratcliffe's daughter sprinted into her mother's arms after she touched down in the UK.
Gabriella was heard asking "is that mummy?" as Nazanin departed the plane at RAF Brize Norton on Thursday morning.
The seven-year-old shouted "mummy" as Nazanin walked down the plane's stairs, with Gabriella then running towards her mum as she entered the airport.
Tears of joy could be heard as the family were reunited, with Nazanin, 43, unable to stop hugging and showering her daughter with kisses.
The incredible moment was captured on film and shared on social media by Elika Ashoori - the daughter of British ex-civil engineer Anoosheh Ashoori, who was also released by Iran and flew home alongside Nazanin.
Mr Ashoori also enjoyed an emotional reunion with his family and was seen embracing his loved ones at the airport.
The 67-year-olds pent more than four years behind bars after being accused of passing intelligence to Mossad, which he denies.
Meanwhile Nazanin endured six years of imprisonment before finally being allowed to come home.
The pair were released after Britain agreed to settle a £400million debt with Iran which dated back to the 1970s.
Nazanin's local MP Tulip Siddiq shared the mother's "first family selfie" since her return to the UK in a post on social media.
Labour's Mrs Siddiq said the Nazanin and her husband Richard spoke with her about Morad Tahbaz, who has not been allowed to leave Iran after being released from prison on furlough.
Mrs Siddiq said they were both "relentless in their pursuit of justice".
Foreign Office Minister James Cleverly said the Government was working to secure the return of Mr Tahbaz, telling BBC Breakfast: "He also has American nationality, which has in the eyes of the Iranians - not in ours - made his case more complicated."
He added: "We will continue to work to secure his release and, obviously, we work in close co-ordination with the US on these issues as well."
In a tweet on Thursday evening, Ms Siddiq said: "So lovely to have uplifting conversations with Richard and Nazanin today.
"They are both relentless in their pursuit of justice and raised the plight of Morad Tahbaz with me.
"Here I was hoping to sleep for a week... "

Lara Symons, 53, chief executive of charity Hostage International, said the organisation had helped many "trauma hostages".
She told the PA news agency: "From that experience, we've learnt that this is a new journey. This is a long journey.
"I think when people think about normal life, they think about the life that they led before and, sadly, to some extent, that is not possible.
"You can't go back to that because both you as a hostage and your family have been changed quite a lot by the experience."
