A couple from North Walsham, shot and wounded in last June's Tunisian terrorist attack, joined other survivors and dignitaries at a national memorial service to honour those killed in the outrage.

Tuesday's Westminster Abbey event paid tribute to the 30 Britons who were among 38 massacred in the resort town of Sousse when gunman Seifeddine Rezgui targeted holidaymakers on the beach and in a hotel before being shot dead by security forces. Terror group Islamic State (IS) claimed responsibility.

Tony and Christine Callaghan travelled from their home in North Walsham to be at the service which was also attended by Prince Harry and Prime Minister David Cameron.

Mr Callaghan, 63, said it had been a: 'long and very emotional day and an absolute pleasure to be there.'

He added: 'The service was a very moving and respectful tribute to those who lost their lives.'

Prince Harry laid a wreath at the Innocent Victims Memorial on behalf of his grandmother the Queen.

During the service, the Prince and the prime minister both read Bible passages before the 900-strong congregation.

Mr Callaghan said they had met many others on Tuesday for the first time after becoming online friends with them through a Facebook page set up for survivors. It had 210 members, many of whom chatted to each other every day.

'It's like having a brand new family. We all had so much to talk about,' said Mr Callaghan, who has recently taken early retirement from his job as a property officer at North Walsham police station.

A bullet grazed his leg in the attack and he said the wound had healed well.

But his wife, 62, whose femur had been shattered, will undergo a fifth operation today at the Norfolk and Norwich University Hospital to replace a steel rod in her leg which has become loose.

She uses a walking frame at home but a wheelchair outdoors and had to retire from her job with the NHS in January.

In the summer Mrs Callaghan faces what the couple hope will be her final operation when a tendon will be transferred to hold her foot at a right angle to help her bear weight on the injured leg.

The pair are still receiving counselling following the outrage and Mr Callaghan said it was an uncertain road ahead but they viewed life as a glass half full and were hopeful about the future.

He added: 'We feel very lucky to be here.'
